-Git - fast, scalable, distributed revision control system
-=========================================================
-
-Git is a fast, scalable, distributed revision control system with an
-unusually rich command set that provides both high-level operations
-and full access to internals.
-
-Git is an Open Source project covered by the GNU General Public
-License version 2 (some parts of it are under different licenses,
-compatible with the GPLv2). It was originally written by Linus
-Torvalds with help of a group of hackers around the net.
-
-Please read the file [INSTALL][] for installation instructions.
-
-Many Git online resources are accessible from <https://git-scm.com/>
-including full documentation and Git related tools.
-
-See [Documentation/gittutorial.txt][] to get started, then see
-[Documentation/giteveryday.txt][] for a useful minimum set of commands, and
-`Documentation/git-<commandname>.txt` for documentation of each command.
-If git has been correctly installed, then the tutorial can also be
-read with `man gittutorial` or `git help tutorial`, and the
-documentation of each command with `man git-<commandname>` or `git help
-<commandname>`.
-
-CVS users may also want to read [Documentation/gitcvs-migration.txt][]
-(`man gitcvs-migration` or `git help cvs-migration` if git is
-installed).
-
-The user discussion and development of Git take place on the Git
-mailing list -- everyone is welcome to post bug reports, feature
-requests, comments and patches to git@vger.kernel.org (read
-[Documentation/SubmittingPatches][] for instructions on patch submission).
-To subscribe to the list, send an email with just "subscribe git" in
-the body to majordomo@vger.kernel.org. The mailing list archives are
-available at <https://public-inbox.org/git/>,
-<http://marc.info/?l=git> and other archival sites.
-
-Issues which are security relevant should be disclosed privately to
-the Git Security mailing list <git-security@googlegroups.com>.
-
-The maintainer frequently sends the "What's cooking" reports that
-list the current status of various development topics to the mailing
-list.  The discussion following them give a good reference for
-project status, development direction and remaining tasks.
-
-The name "git" was given by Linus Torvalds when he wrote the very
-first version. He described the tool as "the stupid content tracker"
-and the name as (depending on your mood):
-
- - random three-letter combination that is pronounceable, and not
-   actually used by any common UNIX command.  The fact that it is a
-   mispronunciation of "get" may or may not be relevant.
- - stupid. contemptible and despicable. simple. Take your pick from the
-   dictionary of slang.
- - "global information tracker": you're in a good mood, and it actually
-   works for you. Angels sing, and a light suddenly fills the room.
- - "goddamn idiotic truckload of sh*t": when it breaks

+depot
+=====
+
+This repository is the [monorepo][] for my personal tools and infrastructure.
+Everything in here is built using [Nix][] with an automatic attribute-set layout
+that mirrors the filesystem layout of the repository (this might feel familiar
+to users of Bazel).
+
+This repository used to be hosted on GitHub, but for a variety of reasons I have
+decided to take over the management of personal infrastructure - of which this
+repository is a core component.
+
+If you've ended up here and have no idea who I am, feel free to follow me [on
+Twitter][].
+
+# Highlights
+
+## Tools
+
+* `tools/emacs` contains my personal Emacs configuration (packages & config)
+* `fun/aoc2019` contains solutions for a handful of Advent of Code 2019
+  challenges, before I ran out of interest
+* `tools/blog_cli` contains my tool for writing new blog posts and storing them
+  in the DNS zone
+* `ops/kms_pass.nix` is a tiny tool that emulates the user-interface of `pass`,
+  but actually uses Google Cloud KMS for secret decryption
+* `ops/kontemplate` contains my Kubernetes resource templating tool (with which
+  the services in this repository are deployed!)
+
+## Packages / Libraries
+
+* `nix/buildGo` implements a Nix library that can build Go software in the style
+  of Bazel's `rules_go`. Go programs in this repository are built using this
+  library.
+* `tools/emacs-pkgs` contains various Emacs libraries that my Emacs setup uses,
+  for example:
+  * `dottime.el` provides [dottime][] in the Emacs modeline
+  * `nix-util.el` provides editing utilities for Nix files
+  * `term-switcher.el` is an ivy-function for switching between vterm buffers
+* `net/alcoholic_jwt` contains an easy-to-use JWT-validation library for Rust
+* `net/crimp` contains a high-level HTTP client using cURL for Rust
+
+## Services
+
+Services in this repository are deployed on a Google Kubernetes Engine cluster
+using [Nixery]().
+
+* `web/tazblog` contains my blog software (serving at [tazj.in][])
+* `web/cgit-taz` contains a slightly patched version of `cgit` that serves my
+  git web interface at [git.tazj.in][]
+* `ops/sync-gcsr` contains a tiny service that synchronises a Google Cloud
+  Source Repository with a local disk path. My `cgit` setup uses this
+  under-the-hood.
+* `ops/journaldriver` contains a small Rust daemon that can forward logs from
+  journald to Stackdriver Logging
+
+## Miscellaneous
+
+Presentations I've given in the past are in the `presentations` folder, these
+cover a variety of topics and some of them have links to recordings.
+
+There's a few fun things in the `fun/` folder, often with context given in the
+README. Check out my [list of the best tools][best-tools] for example.

+A SERMON ON ETHICS AND LOVE
+===========================
+
+One day Mal-2 asked the messenger spirit Saint Gulik to approach the
+Goddess and request Her presence for some desperate advice. Shortly
+afterwards the radio came on by itself, and an ethereal female Voice
+said **YES?**
+
+"O! Eris! Blessed Mother of Man! Queen of Chaos! Daughter of Discord!
+Concubine of Confusion! O! Exquisite Lady, I beseech You to lift a
+heavy burden from my heart!"
+
+**WHAT BOTHERS YOU, MAL? YOU DON'T SOUND WELL.**
+
+"I am filled with fear and tormented with terrible visions of pain.
+Everywhere people are hurting one another, the planet is rampant with
+injustices, whole societies plunder groups of their own people,
+mothers imprison sons, children perish while brothers war. O, woe."
+
+**WHAT IS THE MATTER WITH THAT, IF IT IS WHAT YOU WANT TO DO?**
+
+"But nobody Wants it! Everybody hates it."
+
+**OH. WELL, THEN *STOP*.**
+
+At which moment She turned herself into an aspirin commercial and left
+The Polyfather stranded alone with his species.
+
+SINISTER DEXTER HAS A BROKEN SPIROMETER.

+
+When adding a feature you should consider whether it is only useful for your
+particular use-case or whether it is generally applicable for other users of the
+project.
+
+When in doubt - just ask! You can reach out to me via
+[mail](mailto:mail@tazj.in) or on Twitter / IRC / etc.
+
+## Commit messages
+
+All commit messages should be structured like this:
+
+```
+type(scope): Subject line with at most a 68 character length
+
+Body of the commit message with an empty line between subject and
+body. This text should explain what the change does and why it has
+been made, *especially* if it introduces a new feature.
+
+Relevant issues should be mentioned if they exist.
+```
+
+Where `type` can be one of:
+
+* `feat`: A new feature has been introduced
+* `fix`: An issue of some kind has been fixed
+* `docs`: Documentation or comments have been updated
+* `style`: Formatting changes only
+* `refactor`: Hopefully self-explanatory!
+* `test`: Added missing tests / fixed tests
+* `chore`: Maintenance work
+
+And `scope` should refer to some kind of logical grouping inside of the project.
+
+Please take a look at the existing commit log for examples.
+
+## Commit content
+
+Multiple changes should be divided into multiple git commits whenever possible.
+Common sense applies.
+
+The fix for a single-line whitespace issue is fine to include in a different
+commit. Introducing a new feature and refactoring (unrelated) code in the same
+commit is not fine.
+
+`git commit -a` is generally **taboo**.
+
+In my experience making "sane" commits becomes *significantly* easier as
+developer tooling is improved. The interface to `git` that I recommend is
+[magit][]. Even if you are not yet an Emacs user, it makes sense to install
+Emacs just to be able to use magit - it is really that good.
+
+For staging sane chunks on the command line with only git, consider `git add
+-p`.
+
+## Code quality
+
+This one should go without saying - but please ensure that your code quality
+does not fall below the rest of the project. This is of course very subjective,
+but as an example if you place code that throws away errors into a block in
+which errors are handled properly your change will be rejected.
+
+In my experience there is a strong correlation between the visual appearance of
+a code block and its quality. This is a simple way to sanity-check your work
+while squinting and keeping some distance from your screen ;-)
+
+## Builds & tests
+
+My projects are built using [Nix][] to avoid "build pollution" via the user's
+environment.
+
+If you have Nix installed and are contributing to a project tracked in this
+repository, you can usually build the project by calling `nix-build -A
+path.to.project`.
+
+For example, to build a project located at `tools/foo` you would call `nix-build
+-A tools.foo`
+
+If the project has tests, check that they still work before submitting your
+change.
+
+## Submitting patches
+
+When making a change, please create an appropriate commit locally and send it to
+me using either `git send-email` or `git format-patch`. The email address to use
+for depot reviews is `depot@tazj.in`, which is a [public group][].
+
+I recognise that most people are used to a GitHub-style workflow. If you run
+into issues with the above but would still like to contribute, feel free to
+reach out to me.

+tazjin's best tools
+===================
+
+In the spirit of various other "Which X do you use?"-pages I thought it would be
+fun to have a little document here that describes which tools I've found to work
+well for myself.
+
+When I say "tools" here, it's not about software - it's about real, physical
+tools!
+
+If something goes on this list that's because I think it's seriously a
+best-in-class type of product.

+
+## Keyboard
+
+The best keyboard that money will buy you at the moment is the [Kinesis
+Advantage][advantage]. There's a variety of contoured & similarly shaped
+keyboards on the market, but the Kinesis is the only one I've tried that has
+properly implemented the keywell concept.
+
+I struggle with RSI issues and the Kinesis actually makes it possible for me to
+type for longer periods of time, which always leads to extra discomfort on
+laptop keyboards and such.
+
+Honestly, the Kinesis is probably the best piece of equipment on this entire
+list. I own several of them and there will probably be more in the future. They
+last forever and your wrists will thank you in the future, even if you do not
+suffer from RSI yet.
+
+[advantage]: https://kinesis-ergo.com/shop/advantage2/
+
+## Speakers
+
+The speakers that I've hooked up to my audio setup (including both record player
+& Chromecast / TV) are the [Teufel Motiv 2][motiv-2]. I've had these for over a
+decade and they're incredibly good, but unfortunately Teufel no longer makes
+them.
+
+It's possible to grab a pair on eBay occasionally, so keep an eye out if you're
+interested!
+
+[motiv-2]: https://www.teufelaudio.com/uk/pc/motiv-2-p167.html
+
+## Headphones
+
+I use the [Bose QC35][qc35] (note: link goes to a newer generation than the one
+I own) for their outstanding noise cancelling functionality and decent sound.
+
+When I first bought them I didn't expect them to end up on this list as the
+firmware had issues that made them only barely usable, but Bose has managed to
+iron these problems out over time.
+
+I avoid using Bluetooth when outside and fortunately the QC35 come with an
+optional cable that you can plug into any good old 3.5mm jack.
+
+[qc35]: https://www.bose.co.uk/en_gb/products/headphones/over_ear_headphones/quietcomfort-35-wireless-ii.html
+
+### Earphones
+
+Actually, to follow up on the above - most of the time I'm not using (over-ear)
+headphones, but (in-ear) earphones - specifically the (**wired!!!**) [Apple
+EarPods][earpods].
+
+Apple will probably stop selling these soon because they've gotten into the
+habit of cancelling all of their good products, so I have a stash of these
+around. You will usually find no fewer than 3-4 of them lying around in my
+flat.
+
+[earpods]: https://www.apple.com/uk/shop/product/MNHF2ZM/A/earpods-with-35mm-headphone-plug
+
+## Phone
+
+The best phone that's on the market at the moment is the [iPhone SE][se]. It's
+as far as I am aware the *only* phone that has a reasonable size (up to 4")
+*and* a 3.5mm headphone jack.
+
+These two are the make-it-or-break-it requirements for me. Despite iOS being an
+annoying system to use there is nothing better available at the moment.
+
+This is the only item on this list for which I am actively seeking a
+replacement, so if you have any tips about new phones that might fit these
+criteria that I've missed please let me know.
+
+[se]: https://en.wikipedia.org/wiki/IPhone_SE
+
+# Other stuff
+
+## Toothbrush
+
+The [Philips Sonicare][sonicare] (note: link goes to a newer generation than
+mine) is excellent and well worth its money.
+
+I've had it for a few years and whereas I occasionally had minor teeth issues
+before, they seem to be mostly gone now. According to my dentist the state of my
+teeth is now usually pretty good and I draw a direct correlation back to this
+thing.
+
+The newer generations come with flashy features like apps and probably more
+LEDs, but I suspect that those can just be ignored.
+
+[sonicare]: https://www.philips.co.uk/c-m-pe/electric-toothbrushes
+
+## Shavers
+
+The [Philipps SensoTouch 3D][sensotouch] is excellent. Super-comfortable close
+face shave in no time and leaves absolutely no mess around, as far as I can
+tell! I've had this for ~5 years and it's not showing any signs of aging yet.
+
+Another bonus is that its battery time is effectively infinite. I've never had
+to worry when bringing it on a longer trip!
+

+
+## Shoulder bag
+
+When I moved to London I wanted to stop using backpacks most of the time, as
+those are just annoying to deal with when commuting on the tube.
+
+To work around this I wanted a good shoulder bag with a vertical format (to save
+space), but it turned out that there's very few of those around that reach any

+defer in Rust
+=============
+
+After a Hacker News discussion about implementing Go's `defer` keyword in C++,
+I stumbled upon [this comment](https://news.ycombinator.com/item?id=15523589)
+and more specifically this response to it by "Occivink":
+
+> There's plenty of one-time cases where you don't want to declare an entire
+> class but still enjoy scope-based functions.
+
+Specificall the "don't want to declare an entire class" suggests that languages
+like C++ have high friction for explaining your desired invariant (cleanup is
+run when `$thing` is destroyed) to the compiler.
+
+It seems like most languages either hand-wave this away (*cough* Java *cough*)
+or use what seems like a workaround (`defer`).
+
+Rust has the so-called `Drop` trait, which is a typeclass that contains a single
+method with no return value that is run when a variable is dropped (i.e. goes out
+of scope).
+
+This works fine for most general cases - i.e. closing file handlers - but can
+get complicated if other use-cases of `defer` are considered:
+
+* returning an error-value by mutating a reference in the enclosing scope (oh boy)
+* deferring a decision about when/whether to run cleanup to the caller
+
+While thinking about how to do this with the `Drop` trait I realised that `defer`
+can actually be trivially implemented in Rust, using `Drop`.
+
+A simple implementation of `defer` can be seen in [defer.rs](examples/defer.rs),
+an implementation using shared mutable state for error returns is in the file
+[defer-with-error.rs](examples/defer-with-error.rs) and an implementation that
+allows cleanup to be *cancelled* (don't _actually_ do this, it leaks a pointer)
+is in [undefer.rs](examples/undefer.rs).
+
+Whether any of this is actually useful is not up to me to decide. I haven't
+actually had a real-life need for this.
+
+You can run the examples with `cargo run --example defer`, etc.
+
+## Notes
+
+* `Drop` is not guaranteed to run in case of panics or program aborts, if you
+  need support for that check out [scopeguard](https://github.com/bluss/scopeguard)
+* `undefer` could be implemented safely by, for example, carrying a boolean that
+  by default causes execution to happen but can be flipped to disable it
+

+One day Mal-2 asked the messenger spirit Saint Gulik to approach the Goddess and request Her presence for some desperate advice. Shortly afterwards the radio came on by itself, and an ethereal female Voice said **YES?**
+
+"O! Eris! Blessed Mother of Man! Queen of Chaos! Daughter of Discord! Concubine of Confusion! O! Exquisite Lady, I beseech You to lift a heavy burden from my heart!"
+
+**WHAT BOTHERS YOU, MAL? YOU DON'T SOUND WELL.**
+
+"I am filled with fear and tormented with terrible visions of pain. Everywhere people are hurting one another, the planet is rampant with injustices, whole societies plunder groups of their own people, mothers imprison sons, children perish while brothers war. O, woe."
+
+**WHAT IS THE MATTER WITH THAT, IF IT IS WHAT YOU WANT TO DO?**
+
+"But nobody Wants it! Everybody hates it."

+**OH. WELL, THEN *STOP*.**

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+# Gemma
+
+Gemma is a simple application to track *recurring* tasks, named after Gemma
+Hartley who [wrote an article][] about task distribution issues in households.
+
+## Background
+
+(Skip this if you just want the technical bits)
+
+Gemma's article launched a discussion in my friend circle about what causes an
+uneven distribution of household workload. I theorised that this is not so much
+a gender issue, but mostly a discoverability issue.
+
+Usually one person in a household is aware of what needs to be done, but in many
+cases the "overhead" of delegating the tasks would actually take more time than
+simply doing the task.
+
+I theorise further that the person (or people) who do a smaller share of the
+household work would often do the work if they had a convenient way to become
+aware of what needs to be done. Many times the "household manager" has the
+function of tracking non-obvious tasks like when bedsheets were last changed -
+shouldn't it be possible to actually distribute this information somehow?
+
+## The Project
+
+This project is an initial attempt at sketching out a little application that
+aids with reminding users of recurring tasks. Some basic ideas:
+
+* The system should be blame-free.
+* There should be as little usage overhead as possible so that people actually
+  do use it.
+* It should work mostly passively without much user interaction.
+
+I believe that the basic (*very* simple) idea behind Gemma solves these issues.
+Unfortunately my living situation changed before I actually got to test this out
+in a real-life situation involving multiple people, but feedback from other
+potential test subjects would be welcome! :)
+
+## Overview
+
+Gemma is a Common Lisp application in which a list of recurring tasks is
+declared, together with the *maximum interval* at which they should be completed
+(in days). Example:
+
+```lisp
+;; Bathroom tasks
+(deftask bathroom/wipe-mirror 7)
+(deftask bathroom/wipe-counter 7)
+
+;; Bedroom tasks
+(deftask bedroom/change-sheets 7)
+(deftask bedroom/vacuum 10)
+
+;; Kitchen tasks
+(deftask kitchen/trash 3)
+(deftask kitchen/wipe-counters 3)
+(deftask kitchen/vacuum 5 "Kitchen has more crumbs and such!")
+
+;; Entire place
+(deftask clean-windows 60)
+```
+
+These tasks are marked with their last completion time and tracked by Gemma. A
+simple Elm-based frontend application displays the tasks sorted by their
+"urgency" and features a button to mark a task as completed:
+
+![Gemma screenshot](http://i.imgur.com/n7FFMJH.png)
+
+Marking a task as completed resets its counter and moves it to the bottom of the
+task list.
+
+In theory this *should be it*, the frontend is made available to household
+members in some easily accessible place (e.g. an old phone glued to the fridge!)
+and people should attempt to develop a habit of checking what needs to be done
+occasionally.
+
+The "household manager" still exists as a role of the household because someone
+is entering the tasks into the application, but if my theory about people not
+actually being actively *unwilling* to do tasks is correct this could help a
+lot.
+
+## Usage
+
+(*Note*: Gemma is alpha software so the below is clearly not the final goal)
+
+Right now using this is non-trivial, but I'll eventually make a better
+distribution. Basically you need to know Common Lisp (in which case you'll know
+how to get the backend running) and have `elm-reactor` installed to run the
+development version of the frontend application.
+
+Gemma is configured via a configuration file that should be located either at
+`/etc/gemma/config.lisp` or at a custom location specified via the environment
+variable `GEMMA_CONFIG`. Have a look at the `config.lisp` file in the repository
+root for an example.

+Quinistry
+=========
+
+*A simple Docker registry quine.*
+
+## What?
+
+This is an example project for a from-scratch implementation of an HTTP server compatible with the [Docker Registry V2][]
+protocol.
+
+It serves a single image called `quinistry:latest` which is a Docker image that runs quinistry itself, therefore it is a
+sort of Docker registry [quine][].
+
+The official documentation does not contain enough information to actually implement this protocol (which I assume is
+intentional), but a bit of trial&error lead there anyways. I've added comments to parts of the code to clear up things
+that may be helpful to other developers in the future.
+
+## Example
+
+```
+# Run quinistry:
+vincent@urdhva ~/go/src/github.com/tazjin/quinistry (git)-[master] % ./quinistry
+2017/03/16 14:11:56 Starting quinistry
+
+# Pull the quinistry image from itself:
+vincent@urdhva ~ % docker pull localhost:8080/quinistry
+Using default tag: latest
+latest: Pulling from quinistry
+7bf1a8b18466: Already exists
+Digest: sha256:d5cd4490901ef04b4e28e4ccc03a1d25fe3461200cf4d7166aab86fcd495e22e
+Status: Downloaded newer image for localhost:8080/quinistry:latest
+
+# Quinistry will log:
+2017/03/16 14:14:03 Acknowleding V2 API: GET /v2/
+2017/03/16 14:14:03 Serving manifest: GET /v2/quinistry/manifests/latest
+2017/03/16 14:14:03 Serving config: GET /v2/quinistry/blobs/sha256:fbb165c48849de16017aa398aa9bb08fd1c00eaa7c150b6c2af37312913db279
+
+# Run the downloaded image:
+vincent@urdhva ~ % docker run -p 8090:8080 localhost:8080/quinistry
+2017/03/16 13:15:18 Starting quinistry
+
+# And download it again from itself:
+vincent@urdhva ~ % docker pull localhost:8090/quinistry
+Using default tag: latest
+latest: Pulling from quinistry
+7bf1a8b18466: Already exists
+Digest: sha256:11141d95ddce0bac9ffa32ab1e8bc94748ed923e87762c68858dc41d11a46d3f
+Status: Downloaded newer image for localhost:8090/quinistry:latest
+```
+
+## Building
+
+Quinistry creates a Docker image that only contains a statically linked `main` binary. As this package makes use of
+`net/http`, Go will (by default) link against `libc` for DNS resolution and create a dynamic binary instead.
+
+To disable this, `build` the project with `-tags netgo`:
+
+```
+go build -tags netgo
+```

+Watchblob - WatchGuard VPN on Linux
+===================================
+
+This tiny helper tool makes it possible to use WatchGuard / Firebox / <<whatever
+they are actually called>> VPNs that use multi-factor authentication on Linux.
+
+Rather than using OpenVPN's built-in dynamic challenge/response protocol, WatchGuard
+has opted for a separate implementation negotiating credentials outside of the
+OpenVPN protocol, which makes it impossible to start those connections solely by
+using the `openvpn` CLI and configuration files.
+
+What this application does has been reverse-engineered from the "WatchGuard Mobile VPN
+with SSL" application on OS X.
+
+I've published a [blog post](https://www.tazj.in/en/1486830338) describing the process
+and what is actually going on in this protocol.
+
+## Installation
+
+Make sure you have Go installed and `GOPATH` configured, then simply
+`go get github.com/tazjin/watchblob/...`.
+
+## Usage
+
+Right now the usage is very simple. Make sure you have the correct OpenVPN client
+config ready (this is normally supplied by the WatchGuard UI) simply run:
+
+```
+watchblob vpnserver.somedomain.org username p4ssw0rd
+```
+
+The server responds with a challenge which is displayed to the user, wait until you
+receive the SMS code or whatever and enter it. `watchblob` then completes the
+credential negotiation and you may proceed to log in with OpenVPN using your username
+and *the OTP token* (**not**  your password) as credentials.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see

+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read

+alcoholic_jwt
+=============
+
+[![Build Status](https://travis-ci.org/aprilabank/alcoholic_jwt.svg?branch=master)](https://travis-ci.org/aprilabank/alcoholic_jwt)
+
+This is a library for **validation** of **RS256** JWTs using keys from
+a JWKS. Nothing more, nothing less.
+
+RS256 is the most commonly used asymmetric signature mechanism for
+JWTs, encountered in for example [Google][]'s or [Aprila][]'s APIs.
+
+The name of the library stems from the potential side-effects of
+trying to use the other Rust libraries that are made for similar
+purposes.
+
+## Usage overview
+
+You are retrieving JWTs from some authentication provider that uses
+`RS256` signatures and provides its public keys in [JWKS][] format.
+
+Example for a token that provides the key ID used for signing in the
+[`kid` claim][]:
+
+```rust
+extern crate alcoholic_jwt;
+
+use alcoholic_jwt::{JWKS, Validation, validate, token_kid};
+
+// The function implied here would usually perform an HTTP-GET
+// on the JWKS-URL for an authentication provider and deserialize
+// the result into the `alcoholic_jwt::JWKS`-struct.
+let jwks: JWKS = jwks_fetching_function();
+
+let token: String = some_token_fetching_function();
+
+// Several types of built-in validations are provided:
+let validations = vec![
+  Validation::Issuer("auth.test.aprila.no".into()),
+  Validation::SubjectPresent,
+];
+
+// If a JWKS contains multiple keys, the correct KID first
+// needs to be fetched from the token headers.
+let kid = token_kid(&token)
+    .expect("Failed to decode token headers")
+    .expect("No 'kid' claim present in token");
+
+let jwk = jwks.find(&kid).expect("Specified key not found in set");
+
+validate(token, jwk, validations).expect("Token validation has failed!");
+```
+
+## Under the hood
+
+This library aims to only use trustworthy off-the-shelf components to
+do the work. Cryptographic operations are provided by the `openssl`
+crate, JSON-serialisation is provided by `serde_json`.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.

+
+//! # crimp
+//!
+//! This library provides a simplified API over the [cURL Rust
+//! bindings][] that resemble that of higher-level libraries such as
+//! [reqwest][]. All calls are synchronous.
+//!
+//! `crimp` is intended to be used in situations where HTTP client
+//! functionality is desired without adding a significant number of
+//! dependencies or sacrificing too much usability.
+//!
+//! Using `crimp` to make HTTP requests is done using a simple
+//! builder-pattern style API. For example, to make a `GET`-request
+//! and print the result to `stdout`:
+//!
+//! ```rust
+//! use crimp::Request;
+//!
+//! let response = Request::get("http://httpbin.org/get")
+//!     .user_agent("crimp test suite").unwrap()
+//!     .send().unwrap()
+//!     .as_string().unwrap();
+//!
+//! println!("Status: {}\nBody: {}", response.status, response.body);
+//! # assert_eq!(response.status, 200);
+//! ```
+//!
+//! If a feature from the underlying cURL library is missing, the
+//! `Request::raw` method can be used as an escape hatch to deal with
+//! the handle directly. Should you find yourself doing this, please
+//! [file an issue][].
+//!
+//! `crimp` does not currently expose functionality for re-using a
+//! cURL Easy handle, meaning that keep-alive of HTTP connections and
+//! the like is not supported.
+//!
+//! ## Cargo features
+//!
+//! All optional features are enabled by default.
+//!
+//! * `json`: Adds `Request::json` and `Response::as_json` methods
+//!   which can be used for convenient serialisation of
+//!   request/response bodies using `serde_json`. This feature adds a
+//!   dependency on the `serde` and `serde_json` crates.
+//!
+//! ## Initialisation
+//!
+//! It is recommended to call the underlying `curl::init` method
+//! (re-exported as `crimp::init`) when launching your application to
+//! initialise the cURL library. This is not required, but will
+//! otherwise occur the first time a request is made.

+STOMP on Erlang
+===============
+
+`stomp.erl` is a simple Erlang client for the [STOMP protocol][] in version 1.2.
+
+Currently only subscribing to queues is supported.
+
+It provides an application called `stomp` which takes configuration of the form:
+
+```erlang
+[{stomp, #{host     => "stomp-server.somedomain.sexy", % required
+           port     => 61613,                          % optional
+           login    => <<"someuser">>,                 % optional
+           passcode => <<"hunter2>>,                   % optional
+ }}].
+```
+
+## Types
+
+The following types are used in `stomp.erl`, you can include them from
+`stomp.hrl`:
+
+```erlang
+%% Client ack modes, refer to the STOMP protocol documentation
+-type ack_mode() :: client | client_individual | auto.
+
+%% Subscriptions are enumerated from 0
+-type sub_id() :: integer().
+
+%% Message IDs (for acknowledgements) are simple strings. They are
+%% extracted from the 'ack' field of the header in client or client-individual
+%% mode, and from the 'message-id' field in auto mode.
+-type message_id() :: binary().
+
+%% A STOMP message as received from a queue subscription
+-record(stomp_msg, { headers :: #{ binary() => binary() },
+                     body    :: binary() }.
+-type stomp_msg() :: #stomp_msg{}.
+```
+
+Once the application starts it will register a process under the name
+`stomp_worker` and expose the following API:
+
+## Subscribing to a queue
+
+```erlang
+%% Subscribe to a destination, receive the subscription ID
+-spec subscribe(binary(),   % Destination (e.g. <<"/queue/lizards">>)
+                ack_mode(), % Client-acknowledgement mode
+                -> {ok, sub_id()}.
+```
+
+This synchronous call subscribes to a message queue. The `stomp_worker` will
+link itself to the caller and forward received messages as
+`{msg, sub_id(), stomp_msg()}`.
+
+Depending on the acknowledgement mode specified on connecting, the subscriber
+may have to acknowledge receival of messages.
+
+## Acknowledging messages
+
+```erlang
+%% Acknowledge a message ID.
+%% This is not required in auto mode. In client mode it will acknowledge the
+%% received messages up to the ID specified. In client-individual mode every
+%% single message has to be acknowledged.
+-spec ack(sub_id(), message_id()) -> ok.
+
+%% Explicitly "unacknowledge" a message
+-spec nack(sub_id(), message_id()) -> ok.
+```
+
+Both of these calls are asynchronous and will return immediately. Note that in
+the case of the `stomp_worker` crashing before a message acknowledgement is
+handled, the message *may* be delivered again. Your consumer needs to be able to
+handle this.

+buildGo.nix
+===========
+
+This is an alternative [Nix][] build system for [Go][]. It supports building Go
+libraries and programs, and even automatically generating Protobuf & gRPC
+libraries.
+
+*Note:* This will probably end up being folded into [Nixery][].
+
+## Background
+
+Most language-specific Nix tooling outsources the build to existing
+language-specific build tooling, which essentially means that Nix ends up being
+a wrapper around all sorts of external build systems.
+
+However, systems like [Bazel][] take an alternative approach in which the
+compiler is invoked directly and the composition of programs and libraries stays
+within a single homogeneous build system.
+
+Users don't need to learn per-language build systems and especially for
+companies with large monorepo-setups ([like Google][]) this has huge
+productivity impact.
+
+This project is an attempt to prove that Nix can be used in a similar style to
+build software directly, rather than shelling out to other build systems.
+
+## Example
+
+Given a program layout like this:
+
+```
+.
+├── lib          <-- some library component
+│   ├── bar.go
+│   └── foo.go
+├── api.proto    <-- gRPC API definition
+├── main.go      <-- program implementation
+└── default.nix  <-- build instructions
+```
+
+The contents of `default.nix` could look like this:
+
+```nix
+{ buildGo }:
+
+let
+  api = buildGo.grpc {
+    name  = "someapi";
+    proto = ./api.proto;
+  };
+
+  lib = buildGo.package {
+    name = "somelib";
+    srcs = [
+      ./lib/bar.go
+      ./lib/foo.go
+    ];
+  };
+in buildGo.program {
+  name = "my-program";
+  deps = [ api lib ];
+
+  srcs = [
+    ./main.go
+  ];
+}
+```
+
+(If you don't know how to read Nix, check out [nix-1p][])
+
+## Usage
+
+`buildGo` exposes five different functions:
+
+* `buildGo.program`: Build a Go binary out of the specified source files.
+
+  | parameter | type                    | use                                            | required? |
+  |-----------|-------------------------|------------------------------------------------|-----------|
+  | `name`    | `string`                | Name of the program (and resulting executable) | yes       |
+  | `srcs`    | `list<path>`            | List of paths to source files                  | yes       |
+  | `deps`    | `list<drv>`             | List of dependencies (i.e. other Go libraries) | no        |
+  | `x_defs`  | `attrs<string, string>` | Attribute set of linker vars (i.e. `-X`-flags) | no        |
+
+* `buildGo.package`: Build a Go library out of the specified source files.
+
+  | parameter | type         | use                                            | required? |
+  |-----------|--------------|------------------------------------------------|-----------|
+  | `name`    | `string`     | Name of the library (and resulting executable) | yes       |
+  | `srcs`    | `list<path>` | List of paths to source files                  | yes       |
+  | `deps`    | `list<drv>`  | List of dependencies (i.e. other Go libraries) | no        |
+  | `path`    | `string`     | Go import path for the resulting library       | no        |
+
+* `buildGo.external`: Build an externally defined Go library or program.
+
+  This function performs analysis on the supplied source code (which
+  can use the standard Go tooling layout) and creates a tree of all
+  the packages contained within.
+
+  This exists for compatibility with external libraries that were not
+  defined using buildGo.
+
+  | parameter | type           | use                                           | required? |
+  |-----------|----------------|-----------------------------------------------|-----------|
+  | `path`    | `string`       | Go import path for the resulting package      | yes       |
+  | `src`     | `path`         | Path to the source **directory**              | yes       |
+  | `deps`    | `list<drv>`    | List of dependencies (i.e. other Go packages) | no        |
+
+  For some examples of how `buildGo.external` is used, check out
+  [`proto.nix`](./proto.nix).
+
+* `buildGo.proto`: Build a Go library out of the specified Protobuf definition.
+
+  | parameter   | type        | use                                              | required? |
+  |-------------|-------------|--------------------------------------------------|-----------|
+  | `name`      | `string`    | Name for the resulting library                   | yes       |
+  | `proto`     | `path`      | Path to the Protobuf definition file             | yes       |
+  | `path`      | `string`    | Import path for the resulting Go library         | no        |
+  | `extraDeps` | `list<drv>` | Additional Go dependencies to add to the library | no        |
+
+* `buildGo.grpc`: Build a Go library out of the specified gRPC definition.
+
+  The parameters are identical to `buildGo.proto`.
+
+## Current status
+
+This project is work-in-progress. Crucially it is lacking the following features:
+
+* feature flag parity with Bazel's Go rules
+* documentation building
+* test execution
+
+There are still some open questions around how to structure some of those
+features in Nix.

+buildLisp.nix
+=============
+
+This is a build system for Common Lisp, written in Nix.
+
+The project is in its early stages and currently supports nothing
+other than compiling a bunch of Lisp sources into a combined FASL
+file.
+
+This is what it currently looks like:
+
+```nix
+nix.buildLisp.library {
+  name = "test-lib";
+  srcs = [
+    ./nix/buildLisp/test-lib.lisp
+  ];
+}
+```
+
+Check back here in a few days for more information.

+readTree
+========
+
+This is a Nix program that builds up an attribute set tree for a large
+repository based on the filesystem layout.
+
+It is in fact the tool that lays out the attribute set of this repository.
+
+As an example, consider a root (`.`) of a repository and a layout such as:
+
+```
+.
+├── third_party
+│   ├── default.nix
+│   └── rustpkgs
+│       ├── aho-corasick.nix
+│       └── serde.nix
+└── tools
+    ├── cheddar
+    │   └── default.nix
+    └── roquefort.nix
+```
+
+When `readTree` is called on that tree, it will construct an attribute set with
+this shape:
+
+```nix
+{
+    tools = {
+        cheddar = ...;
+        roquefort = ...;
+    };
+
+    third_party = {
+        # the `default.nix` of this folder might have had arbitrary other
+        # attributes here, such as this:
+        favouriteColour = "orange";
+
+        rustpkgs = {
+            aho-corasick = ...;
+            serde = ...;
+        };
+    };
+}
+```
+
+Every imported Nix file that yields an attribute set will have a `__readTree =
+true;` attribute merged into it.
+
+## Traversal logic
+
+`readTree` will follow any subdirectories of a tree and import all Nix files,
+with some exceptions:
+
+* A folder can declare that its children are off-limit by containing a
+  `.skip-subtree` file. Since the content of the file is not checked, it can be
+  useful to leave a note for a human in the file.
+* If a folder contains a `default.nix` file, no *sibling* Nix files will be
+  imported - however children are traversed as normal.
+* If a folder contains a `default.nix` it is loaded and, if it evaluates to a
+  set, *merged* with the children. If it evaluates to anything else the children
+  are *not traversed*.
+
+Traversal is lazy, `readTree` will only build up the tree as requested. This
+currently has the downside that directories with no importable files end up in
+the tree as empty nodes (`{}`).
+
+## Import structure
+
+`readTree` is called with two parameters: The arguments to pass to all imports,
+and the initial path at which to start the traversal.
+
+The package headers in this repository follow the form `{ pkgs, ... }:` where
+`pkgs` is a fixed-point of the entire package tree (see the `default.nix` at the
+root of the depot).
+
+In theory `readTree` can pass arguments of different shapes, but I have found
+this to be a good solution for the most part.
+
+Note that `readTree` does not currently make functions overridable, though it is
+feasible that it could do that in the future.

+yants
+=====
+
+This is a tiny type-checker for data in Nix, written in Nix.
+
+# Features
+
+* Checking of primitive types (`int`, `string` etc.)
+* Checking polymorphic types (`option`, `list`, `either`)
+* Defining & checking struct/record types
+* Defining & matching enum types
+* Defining & matching sum types
+* Defining function signatures (including curried functions)
+* Types are composable! `option string`! `list (either int (option float))`!
+* Type errors also compose!
+
+Currently lacking:
+
+* Any kind of inference
+* Convenient syntax for attribute-set function signatures
+
+## Primitives & simple polymorphism

+
+## Functions!
+
+![functions](screenshots/functions.png)
+
+# Usage
+
+Yants can be imported from its `default.nix`. A single attribute (`lib`) can be
+passed, which will otherwise be imported from `<nixpkgs>`.
+
+Examples for the most common import methods would be:
+
+1. Import into scope with `with`:
+    ```nix
+    with (import ./default.nix {});
+    # ... Nix code that uses yants ...
+    ```
+
+2. Import as a named variable:
+    ```nix
+    let yants = import ./default.nix {};
+    in yants.string "foo" # or other uses ...
+    ````
+
+3. Overlay into `pkgs.lib`:
+    ```nix
+    # wherever you import your package set (e.g. from <nixpkgs>):
+    import <nixpkgs> {
+      overlays = [
+        (self: super: {
+          lib = super.lib // { yants = import ./default.nix { inherit (super) lib; }; };
+        })
+      ];
+    }
+
+    # yants now lives at lib.yants, besides the other library functions!
+    ```
+
+Please see my [Nix one-pager](https://github.com/tazjin/nix-1p) for more generic
+information about the Nix language and what the above constructs mean.
+
+# Stability
+
+The current API of Yants is **not yet** considered stable, but it works fine and
+should continue to do so even if used at an older version.
+
+Yants' tests use Nix versions above 2.2 - compatibility with older versions is
+not guaranteed.

+journaldriver
+=============
+
+This is a small daemon used to forward logs from `journald` (systemd's
+logging service) to [Stackdriver Logging][].
+
+Many existing log services are written in inefficient dynamic
+languages with error-prone "cover every possible use-case"
+configuration. `journaldriver` instead aims to fit a specific use-case
+very well, instead of covering every possible logging setup.
+
+`journaldriver` can be run on GCP-instances with no additional
+configuration as authentication tokens are retrieved from the
+[metadata server][].

+
+# Features
+
+* `journaldriver` persists the last forwarded position in the journal
+  and will resume forwarding at the same position after a restart
+* `journaldriver` will recognise log entries in JSON format and
+  forward them appropriately to make structured log entries available
+  in Stackdriver
+* `journaldriver` can be used outside of GCP by configuring static
+  credentials
+* `journaldriver` will recognise journald's log priority levels and
+  convert them into equivalent Stackdriver log severity levels
+
+# Usage on Google Cloud Platform
+
+`journaldriver` does not require any configuration when running on GCP
+instances.
+
+1. Install `journaldriver` on the instance from which you wish to
+   forward logs.
+
+2. Ensure that the instance has the appropriate permissions to write
+   to Stackdriver. Google continously changes how IAM is implemented
+   on GCP, so you will have to refer to [Google's documentation][].
+
+   By default instances have the required permissions if Stackdriver
+   Logging support is enabled in the project.
+
+3. Start `journaldriver`, for example via `systemd`.
+
+# Usage outside of Google Cloud Platform
+
+When running outside of GCP, the following extra steps need to be
+performed:
+
+1. Create a Google Cloud Platform service account with the "Log
+   Writer" role and download its private key in JSON-format.
+2. When starting `journaldriver`, configure the following environment
+   variables:
+
+   * `GOOGLE_CLOUD_PROJECT`: Name of the GCP project to which logs
+     should be written.
+   * `GOOGLE_APPLICATION_CREDENTIALS`: Filesystem path to the
+     JSON-file containing the service account's private key.
+   * `LOG_STREAM`: Name of the target log stream in Stackdriver Logging.
+     This will be automatically created if it does not yet exist.
+   * `LOG_NAME`: Name of the target log to write to. This defaults to
+     `journaldriver` if unset, but it is recommended to - for
+     example - set it to the machine hostname.
+
+# Log levels / severities / priorities
+
+`journaldriver` recognises [journald's priorities][] and converts them
+into [equivalent severities][] in Stackdriver. Both sets of values
+correspond to standard `syslog` priorities.
+
+The easiest way to emit log messages with priorites from an
+application is to use [priority prefixes][], which are compatible with
+structured log messages.
+
+For example, to emit a simple warning message (structured and
+unstructured):
+
+```
+$ echo '<4>{"fnord":true, "msg":"structured log (warning)"}' | systemd-cat
+$ echo '<4>unstructured log (warning)' | systemd-cat
+```
+
+# NixOS module
+
+The NixOS package repository [contains a module][] for setting up
+`journaldriver` on NixOS machines. NixOS by default uses `systemd` for
+service management and `journald` for logging, which means that log
+output from most services will be captured automatically.
+
+On a GCP instance the only required option is this:
+
+```nix
+services.journaldriver.enable = true;
+```
+
+When running outside of GCP, the configuration looks as follows:
+
+```nix
+services.journaldriver = {
+  enable                 = true;
+  logStream              = "prod-environment";
+  logName                = "hostname";
+  googleCloudProject     = "gcp-project-name";
+  applicationCredentials = keyFile;
+};
+```
+
+**Note**: The `journaldriver`-module is included in stable releases of
+NixOS since NixOS 18.09.
+
+# Stackdriver Error Reporting
+
+The [Stackdriver Error Reporting][] service of Google's monitoring
+toolbox supports automatically detecting and correlating errors from
+log entries.
+
+To use this functionality log messages must be logged in the expected
+[log format][].
+
+*Note*: Reporting errors from non-GCP instances requires that the
+`LOG_STREAM` environment variable is set to the special value
+`global`.
+
+This value changes the monitored resource descriptor from a log stream
+to the project-global stream. Due to a limitation in Stackdriver Error
+Reporting, this is the only way to correctly ingest errors from
+non-GCP machines. Please see [issue #4][] for more information about
+this.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+Kontemplate - A simple Kubernetes templater
+===========================================
+
+[Kontemplate][] is a simple CLI tool that can take sets of Kubernetes resource
+files with placeholders and insert values per environment.
+
+This tool was made because in many cases all I want in terms of Kubernetes
+configuration is simple value interpolation per environment (i.e. Kubernetes
+cluster), but with the same deployment files.
+
+In my experience this is often enough and more complex solutions such as
+[Helm][] are not required.
+
+Check out a Kontemplate setup example and the feature list below!

+## Features
+
+* [Simple, yet powerful templates](docs/templates.md)
+* [Clean cluster configuration files](docs/cluster-config.md)
+* [Resources organised as simple resource sets](docs/resource-sets.md)
+* Integration with pass
+* Integration with kubectl
+
+## Example
+
+Kontemplate lets you describe resources as you normally would in a simple folder structure:
+
+```
+.
+├── prod-cluster.yaml
+└── some-api
+    ├── deployment.yaml
+    └── service.yaml
+```
+
+This example has all resources belonging to `some-api` (no file naming conventions enforced at all!) in the `some-api`
+folder and the configuration for the cluster `prod-cluster` in the corresponding file.
+
+Lets take a short look at `prod-cluster.yaml`:
+
+```yaml
+---
+context: k8s.prod.mydomain.com
+global:
+  globalVar: lizards
+include:
+  - name: some-api
+    values:
+      version: 1.0-0e6884d
+      importantFeature: true
+      apiPort: 4567
+```
+
+Those values are then templated into the resource files of `some-api`. That's it!
+
+You can also set up more complicated folder structures for organisation, for example:
+
+```
+.
+├── api
+│   ├── image-api
+│   │   └── deployment.yaml
+│   └── music-api
+│       └── deployment.yaml
+│   │   └── default.json
+├── frontend
+│   ├── main-app
+│   │   ├── deployment.yaml
+│   │   └── service.yaml
+│   └── user-page
+│       ├── deployment.yaml
+│       └── service.yaml
+├── prod-cluster.yaml
+└── test-cluster.yaml
+```
+
+And selectively template or apply resources with a command such as
+`kontemplate apply test-cluster.yaml --include api --include frontend/user-page`
+to only update the `api` resource sets and the `frontend/user-page` resource set.
+
+## Installation
+
+It is recommended to install Kontemplate from the signed binary releases available on the
+[releases page][]. Release binaries are available for Linux, OS X, FreeBSD and Windows.
+
+### NixOS
+
+Kontemplate has been included in [NixOS](https://nixos.org/) since version 17.09.
+
+It is available as `kontemplate` from the default Nix package set.
+
+### Arch Linux
+
+An [AUR package][] is available for Arch Linux and other `pacman`-based distributions.
+
+### Building from source
+
+You can clone Kontemplate either by cloning the full
+[depot][https://git.tazj.in/] or by just cloning the kontemplate
+subtree like so:
+
+    git clone -b kontemplate https://git.tazj.in kontemplate
+
+The `go` tooling can be used as normal with this cloned repository. In
+a full clone of the dpeot, Nix can be used to build Kontemplate:
+
+    nix-build -A ops.kontemplate
+
+## Usage
+
+You must have `kubectl` installed to use Kontemplate effectively.
+
+```
+usage: kontemplate [<flags>] <command> [<args> ...]
+
+simple Kubernetes resource templating
+
+Flags:
+  -h, --help                 Show context-sensitive help (also try --help-long and --help-man).
+  -i, --include=INCLUDE ...  Resource sets to include explicitly
+  -e, --exclude=EXCLUDE ...  Resource sets to exclude explicitly
+
+Commands:
+  help [<command>...]
+    Show help.
+
+  template <file>
+    Template resource sets and print them
+
+  apply [<flags>] <file>
+    Template resources and pass to 'kubectl apply'
+
+  replace <file>
+    Template resources and pass to 'kubectl replace'
+
+  delete <file>
+    Template resources and pass to 'kubectl delete'
+
+  create <file>
+    Template resources and pass to 'kubectl create'
+
+```
+
+Examples:
+
+```
+# Look at output for a specific resource set and check to see if it's correct ...
+kontemplate template example/prod-cluster.yaml -i some-api
+
+# ... maybe do a dry-run to see what kubectl would do:
+kontemplate apply example/prod-cluster.yaml --dry-run
+
+# And actually apply it if you like what you see:
+kontemplate apply example/prod-cluster.yaml
+```
+
+Check out the feature list and the individual feature documentation above. Then you should be good to go!

+Cluster configuration
+==========================
+
+Every cluster (or "environment") that requires individual configuration is specified in
+a very simple YAML file in Kontemplate.
+
+An example file for a hypothetical test environment could look like this:
+
+```yaml
+---
+context: k8s.test.mydomain.com
+global:
+  clusterName: test-cluster
+  defaultReplicas: 2
+import:
+  - test-secrets.yaml
+include:
+  - name: gateway
+    path: tools/nginx
+    values:
+      tlsDomains:
+        - test.oslo.pub
+        - test.tazj.in
+  - path: backend
+    values:
+      env: test
+    include:
+      - name: blog
+        values:
+          url: test.tazj.in
+      - name: pub-service
+```

+
+<!-- markdown-toc end -->
+
+## Fields
+
+This is documentation for the individual fields in a cluster context file.
+
+### `context`
+
+The `context` field contains the name of the kubectl-context. You can list context names with
+'kubectl config get-contexts'.
+
+This must be set here so that Kontemplate can use the correct context when calling kubectl.
+
+This field is **required** for `kubectl`-wrapping commands. It can be left out if only the `template`-command is used.
+
+### `global`
+
+The `global` field contains a key/value map of variables that should be available to all resource
+sets in the cluster.
+
+This field is **optional**.
+
+### `import`
+
+The `import` field contains the file names of additional YAML or JSON files from which global
+variables should be loaded. Using this field makes it possible to keep certain configuration that
+is the same for some, but not all, clusters in a common place.
+
+This field is **optional**.
+
+### `include`
+
+The `include` field contains the actual resource sets to be included in the cluster.
+
+Information about the structure of resource sets can be found in the [resource set documentation][].
+
+This field is **required**.
+
+## External variables
+
+As mentioned above, extra variables can be loaded from additional YAML or JSON files. Assuming you
+have a file called `test-secrets.yaml` which contains variables that should be shared between a `test`
+and `dev` cluster, you could import it in your context as such:
+
+```yaml
+# test-secrets.yaml:
+mySecretVar: foo-bar-12345
+
+# test-cluster.yaml:
+context: k8s.test.mydomain.com
+import:
+  - test-secrets.yaml
+
+# dev-cluster.yaml:
+context: k8s.dev.mydomain.com
+import:
+  - test-secrets.yaml
+```
+
+The variable `mySecretVar` is then available as a global variable.

+Resource Sets
+================
+
+Resource sets are collections of Kubernetes resources that should be passed to `kubectl` together.
+
+Technically a resource set is simply a folder with a few YAML and/or JSON templates in it.

+
+<!-- markdown-toc end -->
+
+# Creating resource sets
+
+Simply create a folder in your Kontemplate repository and place a YAML or JSON file in it. These
+files get interpreted as [templates][] during Kontemplate runs and variables (as well as template
+logic or functions) will be interpolated.
+
+Refer to the template documentation for information on how to write templates.
+
+## Default variables
+
+Sometimes it is useful to specify default values for variables that should be interpolated during
+a run if the [cluster configuration][] does not specify a variable explicitly.
+
+This can be done simply by placing a `default.yaml` or `default.json` file in the resource set
+folder and filling it with key/value pairs of the intended default variables.
+
+Kontemplate will error during interpolation if any variables are left unspecified.
+
+# Including resource sets
+
+Under the cluster configuration `include` key resource sets are included and required variables
+are specified. For example:
+
+```yaml
+include:
+  - name: some-api
+    values:
+      version: 1.2-SNAPSHOT
+```
+
+This will include a resource set from a folder called `some-api` and set the specified `version` variable.
+
+## Fields
+
+The available fields when including a resource set are these:
+
+### `name`
+
+The `name` field contains the name of the resource set. This name can be used to refer to the resource set
+when specifying explicit includes or excludes during a run.
+
+By default it is assumed that the `name` is the path to the resource set folder, but this can be overridden.
+
+This field is **required**.
+
+### `path`
+
+The `path` field specifies an explicit path to a resource set folder in the case that it should differ from
+the resource set's `name`.
+
+This field is **optional**.
+
+### `values`
+
+The `values` field specifies key/values pairs of variables that should be available during templating.
+
+This field is **optional**.
+
+### `args`
+
+The `args` field specifies a list of arguments that should be passed to `kubectl`.
+
+This field is **optional**.
+
+### `include`
+
+The `include` field specifies additional resource sets that should be included and that should inherit the
+variables of this resource set.
+
+The fully qualified names of "nested" resource sets are set to `${PARENT_NAME}/${CHILD_NAME}` and paths are
+merged in the same way.
+
+This makes it easy to organise different resource sets as "groups" to include / exclude them collectively
+during runs.
+
+This field is **optional**.
+
+## Multiple includes
+
+Resource sets can be included multiple times with different configurations. In this case it is recommended
+to set the `path` and `name` fields explicitly. For example:
+
+```yaml
+include:
+  - name: forwarder-europe
+    path: tools/forwarder
+    values:
+      source: europe
+  - name: forwarder-asia
+    path: tools/forwarder
+    values:
+      source: asia
+```
+
+The two different configurations can be referred to by their set names, but will use the same resource
+templates with different configurations.
+
+## Nesting resource sets
+
+As mentioned above for the `include` field, resource sets can be nested. This lets users group resource
+sets in logical ways using simple folder structures.
+
+Assuming a folder structure like:
+
+```
+├── backend
+│   ├── auth-api
+│   ├── message-api
+│   └── order-api
+└── frontend
+    ├── app-page
+    └── login-page
+```
+
+With each of these folders being a resource set, they could be included in a cluster configuration like so:
+
+```yaml
+include:
+  - name: backend
+    include:
+      - name: auth-api
+      - name: message-api
+      - name: order-api
+  - name: frontend:
+    include:
+      - name: app-page
+      - name: login-page
+```
+
+Kontemplate could then be run with, for example, `--include backend` to only include the resource sets nested
+in the backend group. Specific resource sets can also be targeted, for example as `--include backend/order-api`.
+
+Variables specified in the parent resource set are inherited by the children.
+
+### Caveats
+
+Two caveats apply that users should be aware of:
+
+1. The parent resource set can not contain any resource templates itself.
+
+2. Only one level of nesting is supported. Specifying `include` again on a nested resource set will be ignored.

+Kontemplate templates
+=====================
+
+The template file format is based on Go's [templating engine][] in combination
+with a small extension library called [sprig][] that adds additional template
+functions.
+
+Go templates can either simply display variables or build more complicated
+*pipelines* in which variables are passed to functions for further processing,
+or in which conditionals are evaluated for more complex template logic.
+
+It is recommended that you check out the Golang [documentation][] for the templating
+engine in addition to the cherry-picked features listed here.

+
+<!-- markdown-toc end -->
+
+## Basic variable interpolation
+
+The basic template format uses `{{ .variableName }}` as the interpolation format.
+
+### Example:
+
+Assuming that you include a resource set as such:
+
+```
+- name: api-gateway
+  values:
+    internalHost: http://my-internal-host/
+```
+
+And the api-gateway resource set includes a ConfigMap (some fields left out for
+the example):
+
+```
+# api-gateway/configmap.yaml:
+---
+kind: ConfigMap
+metadata:
+  name: api-gateway-config
+data:
+  internalHost: {{ .internalHost }}
+```
+
+The resulting output will be:
+
+```
+
+---
+kind: ConfigMap
+metadata:
+  name: api-gateway-config
+data:
+  internalHost: http://my-internal-host/
+```
+
+## Template functions
+
+Go templates support template functions which you can think of as a sort of
+shell-like pipeline where text flows through transformations from left to
+right.
+
+Some template functions come from Go's standard library and are listed in the
+[Go documentation][]. In addition the functions declared by [sprig][] are
+available in kontemplate, as well as five custom functions:
+
+* `json`: Encodes any supplied data structure as JSON.
+* `gitHEAD`: Retrieves the commit hash at Git `HEAD`.
+* `passLookup`: Looks up the supplied key in [pass][].
+* `insertFile`: Insert the contents of the given file in the resource
+  set folder as a string.
+* `insertTemplate`: Insert the contents of the given template in the resource
+  set folder as a string.
+
+## Examples:
+
+```
+# With the following values:
+name: Donald
+certKeyPath: my-website/cert-key
+
+# The following interpolations are possible:
+
+{{ .name | upper }}
+-> DONALD
+
+{{ .name | upper | repeat 2 }}
+-> DONALD DONALD
+
+{{ .certKeyPath | passLookup }}
+-> Returns content of 'my-website/cert-key' from pass
+
+{{ gitHEAD }}
+-> Returns the Git commit hash at HEAD.
+```
+
+## Conditionals & ranges
+
+Some logic is supported in Golang templates and can be used in Kontemplate, too.
+
+With the following values:
+
+```
+useKube2IAM: true
+servicePorts:
+  - 8080
+  - 9090
+```
+
+The following interpolations are possible:
+
+```
+# Conditionally insert something in the template:
+metadata:
+  annotations:
+    foo: bar
+    {{ if .useKube2IAM -}} iam.amazonaws.com/role: my-api {{- end }}
+```
+
+```
+# Iterate over a list of values
+ports:
+  {{ range .servicePorts }}
+  - port: {{ . }}

+Check out the Golang documentation (linked above) for more information about template logic.
+
+## Caveats
+
+Kontemplate does not by itself parse any of the content of the templates, which
+means that it does not validate whether the resources you supply are valid YAML
+or JSON.
+
+You can perform some validation by using `kontemplate apply --dry-run` which
+will make use of the Dry-Run functionality in `kubectl`.

+
+## Update Deployments when ConfigMaps change
+
+Kubernetes does [not currently][] have the ability to perform rolling updates
+of Deployments and other resource types when `ConfigMap` or `Secret` objects
+are updated.
+
+It is possible to make use of annotations and templating functions in
+Kontemplate to force updates to these resources anyways.
+ 
+For example:
+
+```yaml
+# A ConfigMap that contains some configuration for your app
+---
+kind: ConfigMap
+metadata:
+  name: app-config
+data:
+  app.conf: |
+    name: {{ .appName }}
+    foo: bar
+```
+
+Now whenever the `appName` variable changes or we make an edit to the
+`ConfigMap` we would like to update the `Deployment` making use of it, too. We
+can do this by adding a hash of the parsed template to the annotations of the
+created `Pod` objects:
+
+```yaml
+
+---
+kind: Deployment
+metadata:
+  name: app
+spec:
+  template:
+    metadata:
+      annotations:
+        configHash: {{ insertTemplate "app-config.yaml" | sha256sum }}
+    spec:
+      containers:
+        - name: app
+          # Some details omitted ... 
+          volumeMounts:
+            - name: config
+              mountPath: /etc/app/
+      volumes:
+        - name: config
+          configMap:
+            name: app-config
+```
+
+Now any change to the `ConfigMap` - either by directly editing the yaml file or
+via a changed template variable - will cause the annotation to change,
+triggering a rolling update of all relevant pods.
+
+## direnv & pass
+
+Users of `pass` may have multiple different password stores on their machines.
+Assuming that `kontemplate` configuration exists somewhere on the filesystem
+per project, it is easy to use [direnv][] to switch to the correct
+`PASSWORD_STORE_DIR` variable when entering the folder.

+Kontemplate Docker image
+========================
+
+This builds a simple Docker image available on the Docker Hub as `tazjin/kontemplate`.
+
+Builds are automated based on the Dockerfile contained here.
+
+It contains both `kontemplate` and `kubectl` and can be used as part of container-based
+CI pipelines.
+
+`pass` and its dependencies are also installed to enable the use of the `passLookup`
+template function if desired.

+NixOS configuration
+===================
+
+My NixOS configuration! It configures most of the packages I require
+on my systems, sets up Emacs the way I need and does a bunch of other
+interesting things.
+
+System configuration lives in folders for each machine and a custom
+fixed point evaluation (similar to standard NixOS module
+configuration) is used to combine configuration together.
+
+Building `ops.nixos.rebuilder` yields a script that will automatically
+build and activate the newest configuration based on the current
+hostname.
+
+## Configured hosts:
+
+* `nugget` - desktop computer at home
+* ~~`urdhva` - T470s~~ (currently with edef)

+#+TITLE: Bootstrapping, reproducibility, etc.
+#+AUTHOR: Vincent Ambo
+#+DATE: <2018-03-10 Sat>
+
+* Compiler bootstrapping
+  This section contains notes about compiler bootstrapping, the
+  history thereof, which compilers need it - and so on:
+
+** C
+
+** Haskell
+   - self-hosted compiler (GHC)
+
+** Common Lisp
+   CL is fairly interesting in this space because it is a language
+   that is defined via an ANSI standard that compiler implementations
+   normally actually follow!
+
+   CL has several ecosystem components that focus on making
+   abstracting away implementation-specific calls and if a self-hosted
+   compiler is written in CL using those components it can be
+   cross-bootstrapped.
+
+** Python
+
+* A note on runtimes
+  Sometimes the compiler just isn't enough ...
+
+** LLVM
+** JVM
+
+* References
+  https://github.com/mame/quine-relay
+  https://manishearth.github.io/blog/2016/12/02/reflections-on-rusting-trust/
+  https://tests.reproducible-builds.org/debian/reproducible.html
+
+* Slide thoughts:
+  1. Hardware trust has been discussed here a bunch, most recently
+     during the puri.sm talk. Hardware trust is important, as we see
+     with IME, but it's striking that people often take a leap to "I'm
+     now on my trusted Debian with free software".
+
+     Unless you built it yourself from scratch (Spoiler: you haven't)
+     you're placing trust in what is basically foreign binary blobs.
+
+     Agenda: Implications/attack vectors of this, state of the chicken
+     & egg, the topic of reproducibility, what can you do? (Nix!)
+
+  2. Chicken-and-egg issue
+
+     It's an important milestone for a language to become self-hosted:
+     You begin doing a kind of dogfeeding, you begin to enforce
+     reliability & consistency guarantees to avoid having to redo your
+     own codebase constantly and so on.
+
+     However, the implication is now that you need your own compiler
+     to compile itself.
+
+     Common examples:
+     - C/C++ compilers needed to build C/C++ compilers:
+
+       GCC 4.7 was the last version of GCC that could be built with a
+       standard C-compiler, nowadays it is mostly written in C++.
+
+       Certain versions of GCC can be built with LLVM/Clang.
+
+       Clang/LLVM can be compiled by itself and also GCC.
+
+     - Rust was originally written in OCAML but moved to being
+       self-hosted in 2011. Currently rustc-releases are always built
+       with a copy of the previous release.
+
+       It's relatively new so we can build the chain all the way.
+
+     Notable exceptions: Some popular languages are not self-hosted,
+     for example Clojure. Languages also have runtimes, which may be
+     written in something else (e.g. Haskell -> C runtime)
+* How to help:
+  Most of this advice is about reproducible builds, not bootstrapping,
+  as that is a much harder project.
+
+  - fix reproducibility issues listed in Debian's issue tracker (focus
+    on non-Debian specific ones though)
+  - experiment with NixOS / GuixSD to get a better grasp on the
+    problem space of reproducibility
+
+  If you want to contribute to bootstrapping, look at
+  bootstrappable.org and their wiki. Several initiatives such as MES
+  could need help!

+  %% Slide 1:
+  \section{Introduction}
+
+  %% Slide 2:
+  \begin{frame}{Chicken and egg}
+    Self-hosted compilers are often built using themselves, for example:
+
+    \begin{itemize}
+    \item C-family compilers bootstrap themselves \& each other
+    \item (Some!) Common Lisp compilers can bootstrap each other
+    \item \texttt{rustc} bootstraps itself with a previous version
+    \item ... same for many other languages!
+    \end{itemize}
+  \end{frame}
+
+  \begin{frame}{Chicken, egg and ... lizard?}
+    It's not just compilers: Languages have runtimes, too.
+
+    \begin{itemize}
+    \item JVM is implemented in C++
+    \item Erlang-VM is C
+    \item Haskell runtime is C
+    \end{itemize}
+
+    ... we can't ever get away from C, can we?

+      \huge{Could this be exploited?}
+    \end{center}
+  \end{frame}
+
+  %% Slide 4:
+  \begin{frame}{Short interlude: A quine}
+    \begin{center}
+      \begin{code}
+        ((lambda (x) (list x (list 'quote x)))
+        \newline\vspace*{6mm} '(lambda (x) (list x (list 'quote x))))

+
+  %% Slide 6:
+  \begin{frame}{Trusting Trust}
+    An attack described by Ken Thompson in 1983:
+
+    \begin{enumerate}
+    \item Modify a compiler to detect when it's compiling itself.
+    \item Let the modification insert \textit{itself} into the new compiler.
+    \item Add arbitrary attack code to the modification.
+    \item \textit{Optional!} Remove the attack from the source after compilation.
+    \end{enumerate}

+
+  %% Slide 8:
+  \section{Countermeasures}
+
+  %% Slide 9:
+  \begin{frame}{Diverse Double-Compiling}
+    Assume we have:
+
+    \begin{itemize}
+    \item Target language compilers $A$ and $T$
+    \item The source code of $A$: $ S_{A} $
+    \end{itemize}
+  \end{frame}
+
+  %% Slide 10:
+  \begin{frame}{Diverse Double-Compiling}
+    Apply the first stage (functional equivalence):
+
+    \begin{itemize}
+    \item $ X = A(S_{A})$
+    \item $ Y = T(S_{A})$
+    \end{itemize}
+
+    Apply the second stage (bit-for-bit equivalence):
+
+    \begin{itemize}
+    \item $ V = X(S_{A})$
+    \item $ W = Y(S_{A})$
+    \end{itemize}
+
+    Now we have a new problem: Reproducibility!
+  \end{frame}
+
+  %% Slide 11:
+  \begin{frame}{Reproducibility}
+    Bit-for-bit equivalent output is hard, for example:
+
+    \begin{itemize}
+    \item Timestamps in output artifacts
+    \item Non-deterministic linking order in concurrent builds
+    \item Non-deterministic VM \& memory states in outputs
+    \item Randomness in builds (sic!)
+    \end{itemize}
+  \end{frame}
+
+  \begin{frame}{Reproducibility}
+    \begin{center}
+      Without reproducibility, we can never trust that any shipped
+      binary matches the source code!
+    \end{center}
+  \end{frame}
+
+  %% Slide 12:
+  \section{(Partial) State of the Union}
+
+  \begin{frame}{The Desired State}
+    \begin{center}
+      \begin{enumerate}
+      \item Full-source bootstrap!
+      \item All packages reproducible!
+      \end{enumerate}
+    \end{center}
+  \end{frame}
+
+  %% Slide 13:
+  \begin{frame}{Bootstrapping Debian}
+    \begin{itemize}
+    \item Sparse information on the Debian-wiki
+    \item Bootstrapping discussions mostly resolve around new architectures
+    \item GCC is compiled by depending on previous versions of GCC
+    \end{itemize}
+  \end{frame}
+
+  \begin{frame}{Reproducing Debian}
+    Debian has a very active effort for reproducible builds:
+
+    \begin{itemize}
+    \item Organised information about reproducibility status
+    \item Over 90\% reproducibility in Debian package base!
+    \end{itemize}
+  \end{frame}
+
+  \begin{frame}{Short interlude: Nix}
+    \begin{center}
+      \includegraphics[
+        keepaspectratio=true,

+      ]{nixos-logo.png}
+    \end{center}
+  \end{frame}
+
+  \begin{frame}{Bootstrapping NixOS}
+    Nix evaluation can not recurse forever: The bootstrap can not
+    simply depend on a previous GCC.
+
+    Workaround: \texttt{bootstrap-tools} tarball from a previous
+    binary cache is fetched and used.
+
+    An unfortunate magic binary blob ...
+  \end{frame}
+
+  \begin{frame}{Reproducing NixOS}
+    Not all reproducibility patches have been ported from Debian.
+
+    However: Builds are fully repeatable via the Nix fundamentals!
+  \end{frame}
+
+  \section{Future Developments}
+
+  \begin{frame}{Bootstrappable: stage0}
+    Hand-rolled ``Cthulhu's Path to Madness'' hex-programs:
+
+    \begin{itemize}
+    \item No non-auditable binary blobs
+    \item Aims for understandability by 70\% of programmers
+    \item End goal is a full-source bootstrap of GCC
+    \end{itemize}
+  \end{frame}
+
+
+  \begin{frame}{Bootstrappable: MES}
+    Bootstrapping the ``Maxwell Equations of Software'':
+
+    \begin{itemize}
+    \item Minimal C-compiler written in Scheme
+    \item Minimal Scheme-interpreter (currently in C, but intended to
+      be rewritten in stage0 macros)
+    \item End goal is full-source bootstrap of the entire GuixSD
+    \end{itemize}
+  \end{frame}
+
+  \begin{frame}{Other platforms}
+    \begin{itemize}
+    \item Nix for Darwin is actively maintained
+    \item F-Droid Android repository works towards fully reproducible
+      builds of (open) Android software
+    \item Mobile devices (phones, tablets, etc.) are a lost cause at
+      the moment

+- show source of quine-relay
+
+- (demo quine relay?)
+
+- side-note: this program is very, very trustworthy!### 7
+
+Ken Thompson (designer of UNIX and a couple other things!) received Turing award in 1983, and described attack in speech.
+
+- figure out how to detect self-compilation
+- make that modification a quine
+- insert modification into new compiler
+- add attack code to modification
+- remove attack from source, distributed binary will still be compromised! it's like evolution :)### 8
+
+damage potential is basically infinite:
+
+- classic "login" attack
+=> also applicable to other credentials
+
+- attack (weaken) crypto algorithms
+
+- you can probably think of more!### 10
+
+idea being: potential vulnerability would have to work across compilers:
+
+the more compilers we can introduce (e.g. more architectures, different versions, different compilers), the harder it gets for a vulnerability to survive all of those
+
+The more compilers, the merrier! Lisps are pretty good at this.### 11
+
+if we get a bit-mismatch after DDC, not all hope is lost: Maybe the thing just isn't reproducible!
+
+- many reasons for failures
+- timestamps are a classic! artifacts can be build logs, metadata in ZIP-files or whatever
+- non-determinism is the devil
+- sometimes people actively introduce build-randomness (NaCl)### 12
+
+- Does that binary download on the project's website really match the source?
+
+- Your Linux packages are signed by someone - cool - but what does that mean?### 13
+
+Two things should be achieved - gross oversimplification - to get to the ideal "desired state of the union":
+
+1. full-source bootstrap: without ever introducing any binaries, go from nothing to a full Linux distribution
+
+2. when packages are distributed, we should be able to know the expected output of a source package beforehand
+
+=> suddenly binary distributions become a cache! But more on Nix later.### 14
+
+- Debian project does not seem as concerned with bootstrapping as with reproducibility
+- Debian mostly bootstraps on new architectures (using cross-compilation and similar techniques, from an existing binary base)
+- core bootstrap (GCC & friends) is performed with previous Debian version and depending on GCC### 15
+
+... however! Debian cares about reproducibility.
+
+- automated testing of reproducibility
+- information about the status of all packages is made available in repos
+- Over 90% packages of packages are reproducible!
+
+< show reproducible builds website >
+
+Debian is still fundamentally a binary distribution though, but it doesn't have to be that way.### 16
+
+Nix - a purely functional package manager
+
+It's not a new project (10+ years), been discussed here before, has multiple components: package manager, language, NixOS.
+
+Instead of describing *how* to build a thing, Nix describes *what* to build:### 17
+### 19
+
+In Nix, it's impossible to say "GCC is the result of applying GCC to the GCC source", because that happens to be infinite recursion.
+
+Bootstrapping in Nix works by introducing a binary pinned by its full-hash, which was built on some previous Nix version.
+
+Unfortunately also just a magic binary blob ... ### 20
+
+NixOS is not actively porting all of Debian's reproducibility patches, but builds are fully repeatable:
+
+- introducing a malicious compiler would produce a different input hash -> different package
+
+Future slide: hope is not lost! Things are underway.### 21
+
+- bootstrappable.org (demo?) is an umbrella page for several projects working on bootstrappability
+
+- stage0 is an important piece: manually, small, auditable Hex programs to get to a Hex macro expander
+
+- end goal is a full-source bootrap, but pieces are missing### 22
+
+MES is out of the GuixSD circles (explain Guix, GNU Hurd joke)
+
+- idea being that once you have a Lisp, you have all of computing (as Alan Key said)
+
+- includes MesCC in Scheme -> can *almost* make a working tinyCC -> can *almost* make a working gcc 4.7
+
+- minimal Scheme interpreter, currently built in C to get the higher-level stuff to work, goal is rewrite in hex
+- bootstrapping Guix is the end goal### 23
+
+- userspace in Darwin has a Nix project
+- unsure about other BSDs, but if anyone knows - input welcome!
+- F-Droid has reproducible Android packages, but that's also userspace only
+- All other mobile platforms are a lost cause
+
+Generally, all closed-source software is impossible to trust.

+### 1
+13### 2
+Let's talk about servant, which is several things:
+API description DSL, we'll speak about how this DSL works
+and why it's at the type level
+
+Interpretations of the types resulting from that DSL, for example in
+web servers or API clients
+
+Servant is commonly used or implementing services with APIs, or for accessing
+other APIs with a simple, typed client
+### 3
+Why type-level DSLs?
+Type-level DSL:  express *something*, e.g. endpoints of API, on  type level by combining types. Types can be uninhabited
+
+Phil Wadler's: expression problem: things should be extensible both in the cases of a type, and in the functions operating on the type
+Normal data types: can't add new constructors easily
+Servant lifts thisup to simply allow the declaration of new types that can be included in the DSL, and new interpretations that can be attached to the types through typeclasses
+
+APIs become first-class citizens, can pass them around, combine them etc, they are separate from interpretations such as server implementations. In contrast, in most webframeworks, API declaration is implicit
+
+(Mention previous attemps at type-safe web, Yesod / web-routes + boomerang etc)
+### 4
+Three extensions are necessary:
+TypeOperators lets us use infix operators on the type level as constructors
+DataKinds promotes new type declarations to the kind level, makes type-level literals (strings and natural numbers) available, lets us use type-level lists and pairs in combination with typeoperators
+TypeFamilies: Type-level functions, map one set of types to another, come in two forms (type families, non-injective; data families, injective), more powerful than associated types
+### 5
+Here you can see servant's general syntax, we define an API type as a simple alias of some other type combinations
+strings are type-level strings, not actually values, represent path elements
+endpoints are separated by :<|>, all endpoints end in a method with content types and return types
+Capture captures path segments, but there are other combinators, for example for headers
+Everything that is used from the request is expressed in types, enforcing checkability, no "escape hatch" inside handlers to get request
+Every combinator has associated interpretations through typeclasses
+### 6
+Explain type alias, point out Capture
+Server is a type level function (type family), as mentioned earlier
+### 7
+If we expand server (in ghci with kind!) we can see the actual type of the
+function
+### 8
+Lets speak about some interpretations of these things
+### 9
+Servant server is the main interpretation that people are interested in, it's used
+for taking a type specification and creating a server from it
+Based on WAI, the web application interface, common abstraction for web servers which came out of the Yesod project. Implemented by the web server warp, which Yesod runs on
+### 10
+Explain snippet, path gets removed from server type (irrelevant for handler),
+route extracts string to value level
+### 11
+Explain echo server quickly
+### 12
+servant client allows generation of Haskell functions that query the API with the same types
+this makes for easy to use RPC for example
+### 13
+A lot of other interpretations exist for all kinds of things, mock servers for testing, foreign functions in various languages, documentation ...
+### 14
+Demo!
+1. Go quickly through code
+2. Run server, query with curl
+3. Open javascript function
+4. Show JS code in the thing
+5. Open the map itself
+6. Open GHCi, use client
+7. Generate docs
+### 15
+Conclusion
+Servant is pretty good, it's very easy to get started and it's great to raise the level of things that the compiler can tell you about when you do them wrong.
+### 16
+Drawbacks.

+[notes]
+### 1
+### 2
+Let's start off by looking at what an init system is, how they used to work and what systemd does different before we go into more systemd-specific details.
+### 3
+system processes that are started include for example FS mounts, network settings, powertop...
+system services are long-running processes such as daemons, e.g. SSH, database or web servers, session managers, udev ...
+
+orphans: Process whose parent has finished somehow, gets adopted by init system
+-> when a process terminates its parent must call wait() to get its exit() code, if there is no init system adopting orphans the process would become a zombie
+### 4
+Before systemd there were simple init systems that just did the tasks listed on the previous slide.
+Init scripts -> increased greatly in complexity over time, look at incomprehensible skeleton for Debian service init scripts
+Runlevels -> things such as single-user mode, full multiuser mode, reboot, halt
+
+Init will run all the scripts, but it will not do much more than print information on success/failure of started scripts
+
+Init scripts run strictly sequential
+
+Init is unaware of inter-service dependencies, expressed through prefixing scripts with numbers etc.
+
+Init will not watch processes after system is booted -> crashing daemons will not automatically restart
+### 5
+### 6
+How systemd came to be
+
+Considering the lack of process monitoring, problematic things about init scripts -> legacy init systems have drawbacks
+
+Apple had already built launchd, a more featured init system that monitored running processes, could automatically restart them and allowed for certain advanced features -> however it is awful to use and wrap your head around
+
+Lennart Poettering of Pulseaudio fame and Kay Sievers decided to implement a new init system to address these problems, while taking certain clues from Apple's design
+### 7
+Systemd's design goals
+### 8
+No more init scripts with opaque effects -> services are clearly defined units
+Unit dependencies -> systemd can figure out what can be started in parallel
+Process supervision: Unit can be configured in many ways, e.g. always restart, only restart on success etc
+Service logs: We'll talk more about this later
+### 9
+Units are the core component of systemd that users deal with. They define services and everything else that systemd needs to start and manage.
+Note that all these are the names of the respective man page on a system with systemd installed
+Types:
+systemd.service - processes controlled by systemd
+systemd.target - equivalent to "runlevels", grouping of units for synchronisation
+systemd.timer - more powerful replacement of cron that starts other units
+systemd.path - systemd equvialent of inotify, watches files/folders -> launches units
+systemd.socket - expose local IPC or network sockets, launch units on connections
+systemd.device - trigger units when certain devices are connected
+systemd.mount - systemd equivalent of fstab entries
+systemd.swap - like mount
+systemd.slice - unit groups for resource management purposes
+... and a few more specialised ones
+### 10
+Linux cgroups are a new resource management feature added quite a long time ago, but not used much.
+Cgroups can be created manually and processes can be moved into them in order to control resource utilisation
+Few people used them before systemd, limits.conf was often much easier but not as fine-grained
+Systemd changed this
+### 11
+Systemd collects standard output and stderr from all processes into its journal system
+they provide a tool for querying the log, for example grouping service logs together with correct timestamps, querying,
+### 12
+Systemd tooling, most important one is systemctl for general service management
+journalctl is the query and management tool for journald
+systemd-analyze is used for figuring out performance issues, for example by analysing the boot process, can make cool graphs of dependencies
+systemd-cgtop is like top, but not on a process level - it's on a cgroup/slice level, shows combined usage of cgroups
+systemd-cgls lists contents of systemd's cgroups to see which services are in what group
+there also exist a bunch of others that we'll skip for now
+### 13
+### 14
+### 15
+Systemd criticism comes from many directions and usually focuses on a few points
+feature-creep: systemd is absorbing a lot of different services
+### 16
+explain diagram a bit
+### 17
+opaque: as a result, systemd has a lot more internal complexity that people can't easily wrap your mind around. However I argue that unless you're using something like suckless' sinit with your own scripts, you probably have no idea what your init does today anyways
+unstable: this was definitely true even in the first stable release, with the binary log format getting corrupted for example. I haven't personally experienced any trouble with it recently though.
+Another thing is that services start depending on systemd when they shouldn't, a problem for the BSD world (who cares (hey christoph!))
+### 18
+Despite criticism, systemd was adopted rapidly by large portions of the Linux
+Initially in RedHat, because Poettering and co work there and it was clear from the beginning that it would be there
+ArchLinux (which I'm using) and a few others followed suit quite quickly
+Eventually, the big Debian init system discussion - after a lot of flaming - led to Debian adopting it as well, which had a ripple effect for related distros such as Ubuntu which abandoned upstart for it.

+\maketitle
+
+\section{Introduction}
+
+\begin{frame}{What is an init system?}
+  An init system is the first userspace process (PID 1) started in a UNIX-like system. It handles:
+
+  \begin{itemize}
+  \item Starting system processes and services to prepare the environment
+  \item Adopting and ``reaping'' orphaned processes
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Classical init systems}
+  Init systems before systemd - such as SysVinit - were very simple.
+
+  \begin{itemize}
+  \item Services and processes to run are organised into ``init scripts''
+  \item Scripts are linked to specific runlevels
+  \item Init system is configured to boot into a runlevel
+  \end{itemize}
+
+\end{frame}
+
+\section{systemd}
+
+\begin{frame}{Can we do better?}
+  \begin{itemize}
+  \item ``legacy'' init systems have a lot of drawbacks
+  \item Apple is taking a different approach on OS X
+  \item Systemd project was founded to address these issues
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Systemd design goals}
+  \begin{itemize}
+  \item Expressing service dependencies
+  \item Monitoring service status
+  \item Enable parallel service startups
+  \item Ease of use
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Systemd - the basics}
+  \begin{itemize}
+  \item No scripts are executed, only declarative units
+  \item Units have explicit dependencies
+  \item Processes are supervised
+  \item cgroups are utilised to apply resource limits
+  \item Service logs are managed and centrally queryable
+  \item Much more!
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Systemd units}
+  Units specify how and what to start. Several types exist:
+  \begin{code}
+    \small
+    \begin{columns}[T,onlytextwidth]
+      \column{0.5\textwidth}
+      \begin{itemize}
+      \item systemd.service
+      \item systemd.target
+      \item systemd.timer
+      \item systemd.path
+      \item systemd.socket
+      \end{itemize}
+      \column{0.5\textwidth}
+      \begin{itemize}
+      \item systemd.device
+      \item systemd.mount
+      \item systemd.swap
+      \item systemd.slice
+      \end{itemize}
+    \end{columns}
+  \end{code}
+\end{frame}
+
+
+\begin{frame}{Resource management}
+  Systemd utilises Linux \texttt{cgroups} for resource management, specifically CPU, disk I/O and memory usage.
+
+  \begin{itemize}
+  \item Hierarchical setup of groups makes it easy to limit resources for a set of services
+  \item Units can be attached to a \texttt{systemd.slice} for controlling resources for a group of services
+  \item Resource limits can also be specified directly in the unit
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{journald}
+  Systemd comes with an integrated log management solution, replacing software such as \texttt{syslog-ng}.
+  \begin{itemize}
+  \item All process output is collected in the journal
+  \item \texttt{journalctl} tool provides many options for querying and tailing logs
+  \item Children of processes automatically log to the journal as well
+  \item \textbf{Caveat:} Hard to learn initially
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Systemd tooling}
+  A variety of CLI-tools exist for managing systemd systems.
+  \begin{code}
+    \begin{itemize}
+    \item systemctl
+    \item journalctl
+    \item systemd-analyze
+    \item systemd-cgtop
+    \item systemd-cgls
+    \end{itemize}
+  \end{code}
+
+  Let's look at some of them.
+\end{frame}
+
+\section{Demo}
+
+\section{Controversies}
+
+\begin{frame}{Systemd criticism}
+  Systemd has been heavily criticised, usually focusing around a few points:
+  \begin{itemize}
+  \item Feature-creep: Systemd absorbs more and more other services
+  \end{itemize}
+\end{frame}
+

+\end{frame}
+
+\begin{frame}{Systemd criticism}
+  Systemd has been heavily criticised, usually focusing around a few points:
+  \begin{itemize}
+  \item Feature-creep: Systemd absorbs more and more other services
+  \item Opaque: systemd's inner workings are harder to understand than old \texttt{init}
+  \item Unstable: development is quick and breakage happens
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Systemd adoption}
+  Systemd was initially adopted by RedHat (and related distributions).
+
+  It spread quickly to others, for example ArchLinux.
+
+  Debian and Ubuntu were the last major players who decided to adopt it, but not without drama.

+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+cgit - CGI for Git
+==================
+
+This is an attempt to create a fast web interface for the Git SCM, using a
+built-in cache to decrease server I/O pressure.
+
+Installation
+------------
+
+Building cgit involves building a proper version of Git. How to do this
+depends on how you obtained the cgit sources:
+
+a) If you're working in a cloned cgit repository, you first need to
+initialize and update the Git submodule:
+
+    $ git submodule init     # register the Git submodule in .git/config
+    $ $EDITOR .git/config    # if you want to specify a different url for git
+    $ git submodule update   # clone/fetch and checkout correct git version
+
+b) If you're building from a cgit tarball, you can download a proper git
+version like this:
+
+    $ make get-git
+
+When either a) or b) has been performed, you can build and install cgit like
+this:
+
+    $ make
+    $ sudo make install
+
+This will install `cgit.cgi` and `cgit.css` into `/var/www/htdocs/cgit`. You
+can configure this location (and a few other things) by providing a `cgit.conf`
+file (see the Makefile for details).
+
+If you'd like to compile without Lua support, you may use:
+
+    $ make NO_LUA=1
+
+And if you'd like to specify a Lua implementation, you may use:
+
+    $ make LUA_PKGCONFIG=lua5.1
+
+If this is not specified, the Lua implementation will be auto-detected,
+preferring LuaJIT if many are present. Acceptable values are generally "lua",
+"luajit", "lua5.1", and "lua5.2".
+
+
+Dependencies
+------------
+
+* libzip
+* libcrypto (OpenSSL)
+* libssl (OpenSSL)
+* optional: luajit or lua, most reliably used when pkg-config is available
+
+Apache configuration
+--------------------
+
+A new `Directory` section must probably be added for cgit, possibly something
+like this:
+
+    <Directory "/var/www/htdocs/cgit/">
+        AllowOverride None
+        Options +ExecCGI
+        Order allow,deny
+        Allow from all
+    </Directory>
+
+
+Runtime configuration
+---------------------
+
+The file `/etc/cgitrc` is read by cgit before handling a request. In addition
+to runtime parameters, this file may also contain a list of repositories
+displayed by cgit (see `cgitrc.5.txt` for further details).
+
+The cache
+---------
+
+When cgit is invoked it looks for a cache file matching the request and
+returns it to the client. If no such cache file exists (or if it has expired),
+the content for the request is written into the proper cache file before the
+file is returned.
+
+If the cache file has expired but cgit is unable to obtain a lock for it, the
+stale cache file is returned to the client. This is done to favour page
+throughput over page freshness.
+
+The generated content contains the complete response to the client, including
+the HTTP headers `Modified` and `Expires`.
+
+Online presence
+---------------
+
+* The cgit homepage is hosted by cgit at <https://git.zx2c4.com/cgit/about/>
+
+* Patches, bug reports, discussions and support should go to the cgit
+  mailing list: <cgit@lists.zx2c4.com>. To sign up, visit
+  <https://lists.zx2c4.com/mailman/listinfo/cgit>

+CGITRC(5)
+========
+
+
+NAME
+----
+cgitrc - runtime configuration for cgit
+
+
+SYNOPSIS
+--------
+Cgitrc contains all runtime settings for cgit, including the list of git
+repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank
+lines, and lines starting with '#', are ignored.
+
+
+LOCATION
+--------
+The default location of cgitrc, defined at compile time, is /etc/cgitrc. At
+runtime, cgit will consult the environment variable CGIT_CONFIG and, if
+defined, use its value instead.
+
+
+GLOBAL SETTINGS
+---------------
+about-filter::
+	Specifies a command which will be invoked to format the content of
+	about pages (both top-level and for each repository). The command will
+	get the content of the about-file on its STDIN, the name of the file
+	as the first argument, and the STDOUT from the command will be
+	included verbatim on the about page. Default value: none. See
+	also: "FILTER API".
+
+agefile::
+	Specifies a path, relative to each repository path, which can be used
+	to specify the date and time of the youngest commit in the repository.
+	The first line in the file is used as input to the "parse_date"
+	function in libgit. Recommended timestamp-format is "yyyy-mm-dd
+	hh:mm:ss". You may want to generate this file from a post-receive
+	hook. Default value: "info/web/last-modified".
+
+auth-filter::
+	Specifies a command that will be invoked for authenticating repository
+	access. Receives quite a few arguments, and data on both stdin and
+	stdout for authentication processing. Details follow later in this
+	document. If no auth-filter is specified, no authentication is
+	performed. Default value: none. See also: "FILTER API".
+
+branch-sort::
+	Flag which, when set to "age", enables date ordering in the branch ref
+	list, and when set to "name" enables ordering by branch name. Default
+	value: "name".
+
+cache-about-ttl::
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of the repository about page. See also: "CACHE". Default
+	value: "15".
+
+cache-dynamic-ttl::
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of repository pages accessed without a fixed SHA1. See also:
+	"CACHE". Default value: "5".
+
+cache-repo-ttl::
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of the repository summary page. See also: "CACHE". Default
+	value: "5".
+
+cache-root::
+	Path used to store the cgit cache entries. Default value:
+	"/var/cache/cgit". See also: "MACRO EXPANSION".
+
+cache-root-ttl::
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of the repository index page. See also: "CACHE". Default
+	value: "5".
+
+cache-scanrc-ttl::
+	Number which specifies the time-to-live, in minutes, for the result
+	of scanning a path for git repositories. See also: "CACHE". Default
+	value: "15".
+
+case-sensitive-sort::
+	Sort items in the repo list case sensitively. Default value: "1".
+	See also: repository-sort, section-sort.
+
+cache-size::
+	The maximum number of entries in the cgit cache. When set to "0",
+	caching is disabled. See also: "CACHE". Default value: "0"
+
+cache-snapshot-ttl::
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of snapshots. See also: "CACHE". Default value: "5".
+
+cache-static-ttl::
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of repository pages accessed with a fixed SHA1. See also:
+	"CACHE". Default value: -1".
+
+clone-prefix::
+	Space-separated list of common prefixes which, when combined with a
+	repository url, generates valid clone urls for the repository. This
+	setting is only used if `repo.clone-url` is unspecified. Default value:
+	none.
+
+clone-url::
+	Space-separated list of clone-url templates. This setting is only
+	used if `repo.clone-url` is unspecified. Default value: none. See
+	also: "MACRO EXPANSION", "FILTER API".
+
+commit-filter::
+	Specifies a command which will be invoked to format commit messages.
+	The command will get the message on its STDIN, and the STDOUT from the
+	command will be included verbatim as the commit message, i.e. this can
+	be used to implement bugtracker integration. Default value: none.
+	See also: "FILTER API".
+
+commit-sort::
+	Flag which, when set to "date", enables strict date ordering in the
+	commit log, and when set to "topo" enables strict topological
+	ordering. If unset, the default ordering of "git log" is used. Default
+	value: unset.
+
+css::
+	Url which specifies the css document to include in all cgit pages.
+	Default value: "/cgit.css".
+
+email-filter::
+	Specifies a command which will be invoked to format names and email
+	address of committers, authors, and taggers, as represented in various
+	places throughout the cgit interface. This command will receive an
+	email address and an origin page string as its command line arguments,
+	and the text to format on STDIN. It is to write the formatted text back
+	out onto STDOUT. Default value: none. See also: "FILTER API".
+
+embedded::
+	Flag which, when set to "1", will make cgit generate a html fragment
+	suitable for embedding in other html pages. Default value: none. See
+	also: "noheader".
+
+enable-blame::
+	Flag which, when set to "1", will allow cgit to provide a "blame" page
+	for files, and will make it generate links to that page in appropriate
+	places. Default value: "0".
+
+enable-commit-graph::
+	Flag which, when set to "1", will make cgit print an ASCII-art commit
+	history graph to the left of the commit messages in the repository
+	log page. Default value: "0".
+
+enable-filter-overrides::
+	Flag which, when set to "1", allows all filter settings to be
+	overridden in repository-specific cgitrc files. Default value: none.
+
+enable-follow-links::
+	Flag which, when set to "1", allows users to follow a file in the log
+	view.  Default value: "0".
+
+enable-git-config::
+	Flag which, when set to "1", will allow cgit to use git config to set
+	any repo specific settings. This option is used in conjunction with
+	"scan-path", and must be defined prior, to augment repo-specific
+	settings. The keys gitweb.owner, gitweb.category, gitweb.description,
+	and gitweb.homepage will map to the cgit keys repo.owner, repo.section,
+	repo.desc, and repo.homepage respectively. All git config keys that begin
+	with "cgit." will be mapped to the corresponding "repo." key in cgit.
+	Default value: "0". See also: scan-path, section-from-path.
+
+enable-http-clone::
+	If set to "1", cgit will act as a dumb HTTP endpoint for git clones.
+	You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
+	to expose this feature. If you use an alternate way of serving git
+	repositories, you may wish to disable this. Default value: "1".
+
+enable-html-serving::
+	Flag which, when set to "1", will allow the /plain handler to serve
+	mimetype headers that result in the file being treated as HTML by the
+	browser. When set to "0", such file types are returned instead as
+	text/plain or application/octet-stream. Default value: "0". See also:
+	"repo.enable-html-serving".
+
+enable-index-links::
+	Flag which, when set to "1", will make cgit generate extra links for
+	each repo in the repository index (specifically, to the "summary",
+	"commit" and "tree" pages). Default value: "0".
+
+enable-index-owner::
+	Flag which, when set to "1", will make cgit display the owner of
+	each repo in the repository index. Default value: "1".
+
+enable-log-filecount::
+	Flag which, when set to "1", will make cgit print the number of
+	modified files for each commit on the repository log page. Default
+	value: "0".
+
+enable-log-linecount::
+	Flag which, when set to "1", will make cgit print the number of added
+	and removed lines for each commit on the repository log page. Default
+	value: "0".
+
+enable-remote-branches::
+	Flag which, when set to "1", will make cgit display remote branches
+	in the summary and refs views. Default value: "0". See also:
+	"repo.enable-remote-branches".
+
+enable-subject-links::
+	Flag which, when set to "1", will make cgit use the subject of the
+	parent commit as link text when generating links to parent commits
+	in commit view. Default value: "0". See also:
+	"repo.enable-subject-links".
+
+enable-tree-linenumbers::
+	Flag which, when set to "1", will make cgit generate linenumber links
+	for plaintext blobs printed in the tree view. Default value: "1".
+
+favicon::
+	Url used as link to a shortcut icon for cgit. It is suggested to use
+	the value "/favicon.ico" since certain browsers will ignore other
+	values. Default value: "/favicon.ico".
+
+footer::
+	The content of the file specified with this option will be included
+	verbatim at the bottom of all pages (i.e. it replaces the standard
+	"generated by..." message. Default value: none.
+
+head-include::
+	The content of the file specified with this option will be included
+	verbatim in the html HEAD section on all pages. Default value: none.
+
+header::
+	The content of the file specified with this option will be included
+	verbatim at the top of all pages. Default value: none.
+
+include::
+	Name of a configfile to include before the rest of the current config-
+	file is parsed. Default value: none. See also: "MACRO EXPANSION".
+
+local-time::
+	Flag which, if set to "1", makes cgit print commit and tag times in the
+	servers timezone. Default value: "0".
+
+logo::
+	Url which specifies the source of an image which will be used as a logo
+	on all cgit pages. Default value: "/cgit.png".
+
+logo-link::
+	Url loaded when clicking on the cgit logo image. If unspecified the
+	calculated url of the repository index page will be used. Default
+	value: none.
+
+max-atom-items::
+	Specifies the number of items to display in atom feeds view. Default
+	value: "10".
+
+max-blob-size::
+	Specifies the maximum size of a blob to display HTML for in KBytes.
+	Default value: "0" (limit disabled).
+
+max-commit-count::
+	Specifies the number of entries to list per page in "log" view. Default
+	value: "50".
+
+max-message-length::
+	Specifies the maximum number of commit message characters to display in
+	"log" view. Default value: "80".
+
+max-repo-count::
+	Specifies the number of entries to list per page on the	repository
+	index page. Default value: "50".
+
+max-repodesc-length::
+	Specifies the maximum number of repo description characters to display
+	on the repository index page. Default value: "80".
+
+max-stats::
+	Set the default maximum statistics period. Valid values are "week",
+	"month", "quarter" and "year". If unspecified, statistics are
+	disabled. Default value: none. See also: "repo.max-stats".
+
+mimetype.<ext>::
+	Set the mimetype for the specified filename extension. This is used
+	by the `plain` command when returning blob content.
+
+mimetype-file::
+	Specifies the file to use for automatic mimetype lookup. If specified
+	then this field is used as a fallback when no "mimetype.<ext>" match is
+	found. If unspecified then no such lookup is performed. The typical file
+	to use on a Linux system is /etc/mime.types. The format of the file must
+	comply to:
+	- a comment line is an empty line or a line starting with a hash (#),
+	  optionally preceded by whitespace
+	- a non-comment line starts with the mimetype (like image/png), followed
+	  by one or more file extensions (like jpg), all separated by whitespace
+	Default value: none. See also: "mimetype.<ext>".
+
+module-link::
+	Text which will be used as the formatstring for a hyperlink when a
+	submodule is printed in a directory listing. The arguments for the
+	formatstring are the path and SHA1 of the submodule commit. Default
+	value: none.
+
+noplainemail::
+	If set to "1" showing full author email addresses will be disabled.
+	Default value: "0".
+
+noheader::
+	Flag which, when set to "1", will make cgit omit the standard header
+	on all pages. Default value: none. See also: "embedded".
+
+owner-filter::
+	Specifies a command which will be invoked to format the Owner
+	column of the main page.  The command will get the owner on STDIN,
+	and the STDOUT from the command will be included verbatim in the
+	table.  This can be used to link to additional context such as an
+	owners home page.  When active this filter is used instead of the
+	default owner query url.  Default value: none.
+	See also: "FILTER API".
+
+project-list::
+	A list of subdirectories inside of scan-path, relative to it, that
+	should loaded as git repositories. This must be defined prior to
+	scan-path. Default value: none. See also: scan-path, "MACRO
+	EXPANSION".
+
+readme::
+	Text which will be used as default value for "repo.readme". Multiple
+	config keys may be specified, and cgit will use the first found file
+	in this list. This is useful in conjunction with scan-path. Default
+	value: none. See also: scan-path, repo.readme.
+
+remove-suffix::
+	If set to "1" and scan-path is enabled, if any repositories are found
+	with a suffix of ".git", this suffix will be removed for the url and
+	name. This must be defined prior to scan-path. Default value: "0".
+	See also: scan-path.
+
+renamelimit::
+	Maximum number of files to consider when detecting renames. The value
+	 "-1" uses the compiletime value in git (for further info, look at
+	  `man git-diff`). Default value: "-1".
+
+repository-sort::
+	The way in which repositories in each section are sorted. Valid values
+	are "name" for sorting by the repo name or "age" for sorting by the
+	most recently updated repository. Default value: "name". See also:
+	section, case-sensitive-sort, section-sort.
+
+robots::
+	Text used as content for the "robots" meta-tag. Default value:
+	"index, nofollow".
+
+root-desc::
+	Text printed below the heading on the repository index page. Default
+	value: "a fast webinterface for the git dscm".
+
+root-readme::
+	The content of the file specified with this option will be included
+	verbatim below the "about" link on the repository index page. Default
+	value: none.
+
+root-title::
+	Text printed as heading on the repository index page. Default value:
+	"Git Repository Browser".
+
+scan-hidden-path::
+	If set to "1" and scan-path is enabled, scan-path will recurse into
+	directories whose name starts with a period ('.'). Otherwise,
+	scan-path will stay away from such directories (considered as
+	"hidden"). Note that this does not apply to the ".git" directory in
+	non-bare repos. This must be defined prior to scan-path.
+	Default value: 0. See also: scan-path.
+
+scan-path::
+	A path which will be scanned for repositories. If caching is enabled,
+	the result will be cached as a cgitrc include-file in the cache
+	directory. If project-list has been defined prior to scan-path,
+	scan-path loads only the directories listed in the file pointed to by
+	project-list. Be advised that only the global settings taken
+	before the scan-path directive will be applied to each repository.
+	Default value: none. See also: cache-scanrc-ttl, project-list,
+	"MACRO EXPANSION".
+
+section::
+	The name of the current repository section - all repositories defined
+	after this option will inherit the current section name. Default value:
+	none.
+
+section-sort::
+	Flag which, when set to "1", will sort the sections on the repository
+	listing by name. Set this flag to "0" if the order in the cgitrc file should
+	be preserved. Default value: "1". See also: section,
+	case-sensitive-sort, repository-sort.
+
+section-from-path::
+	A number which, if defined prior to scan-path, specifies how many
+	path elements from each repo path to use as a default section name.
+	If negative, cgit will discard the specified number of path elements
+	above the repo directory. Default value: "0".
+
+side-by-side-diffs::
+	If set to "1" shows side-by-side diffs instead of unidiffs per
+	default. Default value: "0".
+
+snapshots::
+	Text which specifies the default set of snapshot formats that cgit
+	generates links for. The value is a space-separated list of zero or
+	more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
+	The special value "all" enables all snapshot formats.
+	Default value: none.
+
+source-filter::
+	Specifies a command which will be invoked to format plaintext blobs
+	in the tree view. The command will get the blob content on its STDIN
+	and the name of the blob as its only command line argument. The STDOUT
+	from the command will be included verbatim as the blob contents, i.e.
+	this can be used to implement e.g. syntax highlighting. Default value:
+	none. See also: "FILTER API".
+
+summary-branches::
+	Specifies the number of branches to display in the repository "summary"
+	view. Default value: "10".
+
+summary-log::
+	Specifies the number of log entries to display in the repository
+	"summary" view. Default value: "10".
+
+summary-tags::
+	Specifies the number of tags to display in the repository "summary"
+	view. Default value: "10".
+
+strict-export::
+	Filename which, if specified, needs to be present within the repository
+	for cgit to allow access to that repository. This can be used to emulate
+	gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
+	repositories to match those exported by git-daemon. This option must
+	be defined prior to scan-path.
+
+virtual-root::
+	Url which, if specified, will be used as root for all cgit links. It
+	will also cause cgit to generate 'virtual urls', i.e. urls like
+	'/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
+	value: none.
+	NOTE: cgit has recently learned how to use PATH_INFO to achieve the
+	same kind of virtual urls, so this option will probably be deprecated.
+

+	Prefix to use for snapshot links instead of the repository basename.
+	For example, the "linux-stable" repository may wish to set this to
+	"linux" so that snapshots are in the format "linux-3.15.4" instead
+	of "linux-stable-3.15.4".  Default value: <empty> meaning to use
+	the repository basename.
+
+repo.source-filter::
+	Override the default source-filter. Default value: none. See also:
+	"enable-filter-overrides". See also: "FILTER API".

+	setting specified for each repo. Default value: none.
+
+
+REPOSITORY-SPECIFIC CGITRC FILE
+-------------------------------
+When the option "scan-path" is used to auto-discover git repositories, cgit
+will try to parse the file "cgitrc" within any found repository. Such a
+repo-specific config file may contain any of the repo-specific options
+described above, except "repo.url" and "repo.path". Additionally, the "filter"
+options are only acknowledged in repo-specific config files when
+"enable-filter-overrides" is set to "1".
+
+Note: the "repo." prefix is dropped from the option names in repo-specific
+config files, e.g. "repo.desc" becomes "desc".
+
+
+FILTER API
+----------
+By default, filters are separate processes that are executed each time they
+are needed.  Alternative technologies may be used by prefixing the filter
+specification with the relevant string; available values are:
+
+'exec:'::
+	The default "one process per filter" mode.
+
+'lua:'::
+	Executes the script using a built-in Lua interpreter. The script is
+	loaded once per execution of cgit, and may be called multiple times
+	during cgit's lifetime, making it a good choice for repeated filters
+	such as the 'email filter'. It responds to three functions:
+
+	'filter_open(argument1, argument2, argument3, ...)'::
+		This is called upon activation of the filter for a particular
+		set of data.
+	'filter_write(buffer)'::
+		This is called whenever cgit writes data to the webpage.
+	'filter_close()'::
+		This is called when the current filtering operation is
+		completed. It must return an integer value. Usually 0
+		indicates success.
+
+	Additionally, cgit exposes to the Lua the following built-in functions:
+
+	'html(str)'::
+		Writes 'str' to the webpage.
+	'html_txt(str)'::
+		HTML escapes and writes 'str' to the webpage.
+	'html_attr(str)'::
+		HTML escapes for an attribute and writes "str' to the webpage.
+	'html_url_path(str)'::
+		URL escapes for a path and writes 'str' to the webpage.
+	'html_url_arg(str)'::
+		URL escapes for an argument and writes 'str' to the webpage.
+	'html_include(file)'::
+		Includes 'file' in webpage.
+
+
+Parameters are provided to filters as follows.
+
+about filter::
+	This filter is given a single parameter: the filename of the source
+	file to filter. The filter can use the filename to determine (for
+	example) the type of syntax to follow when formatting the readme file.
+	The about text that is to be filtered is available on standard input
+	and the filtered text is expected on standard output.
+
+auth filter::
+	The authentication filter receives 12 parameters:
+	  - filter action, explained below, which specifies which action the
+	    filter is called for
+	  - http cookie
+	  - http method
+	  - http referer
+	  - http path
+	  - http https flag
+	  - cgit repo
+	  - cgit page
+	  - cgit url
+	  - cgit login url
+	When the filter action is "body", this filter must write to output the
+	HTML for displaying the login form, which POSTs to the login url. When
+	the filter action is "authenticate-cookie", this filter must validate
+	the http cookie and return a 0 if it is invalid or 1 if it is invalid,
+	in the exit code / close function. If the filter action is
+	"authenticate-post", this filter receives POST'd parameters on
+	standard input, and should write a complete CGI response, preferably
+	with a 302 redirect, and write to output one or more "Set-Cookie"
+	HTTP headers, each followed by a newline.
+
+	Please see `filters/simple-authentication.lua` for a clear example
+	script that may be modified.
+
+commit filter::
+	This filter is given no arguments. The commit message text that is to
+	be filtered is available on standard input and the filtered text is
+	expected on standard output.
+
+email filter::
+	This filter is given two parameters: the email address of the relevant
+	author and a string indicating the originating page. The filter will
+	then receive the text string to format on standard input and is
+	expected to write to standard output the formatted text to be included
+	in the page.
+
+owner filter::
+	This filter is given no arguments.  The owner text is available on
+	standard input and the filter is expected to write to standard
+	output.  The output is included in the Owner column.
+
+source filter::
+	This filter is given a single parameter: the filename of the source
+	file to filter. The filter can use the filename to determine (for
+	example) the syntax highlighting mode. The contents of the source
+	file that is to be filtered is available on standard input and the
+	filtered contents is expected on standard output.
+
+
+All filters are handed the following environment variables:
+
+- CGIT_REPO_URL (from repo.url)
+- CGIT_REPO_NAME (from repo.name)
+- CGIT_REPO_PATH (from repo.path)
+- CGIT_REPO_OWNER (from repo.owner)
+- CGIT_REPO_DEFBRANCH (from repo.defbranch)
+- CGIT_REPO_SECTION (from repo.section)
+- CGIT_REPO_CLONE_URL (from repo.clone-url)
+
+If a setting is not defined for a repository and the corresponding global
+setting is also not defined (if applicable), then the corresponding
+environment variable will be unset.
+
+
+MACRO EXPANSION
+---------------
+The following cgitrc options support a simple macro expansion feature,
+where tokens prefixed with "$" are replaced with the value of a similarly
+named environment variable:
+
+- cache-root
+- include
+- project-list
+- scan-path
+
+Macro expansion will also happen on the content of $CGIT_CONFIG, if
+defined.
+
+One usage of this feature is virtual hosting, which in its simplest form
+can be accomplished by adding the following line to /etc/cgitrc:
+
+	include=/etc/cgitrc.d/$HTTP_HOST
+
+The following options are expanded during request processing, and support
+the environment variables defined in "FILTER API":
+
+- clone-url
+- repo.clone-url
+
+
+CACHE
+-----
+
+All cache ttl values are in minutes. Negative ttl values indicate that a page
+type will never expire, and thus the first time a URL is accessed, the result
+will be cached indefinitely, even if the underlying git repository changes.
+Conversely, when a ttl value is zero, the cache is disabled for that
+particular page type, and the page type is never cached.
+
+SIGNATURES
+----------
+
+Cgit can host .asc signatures corresponding to various snapshot formats,
+through use of git notes. For example, the following command may be used to
+add a signature to a .tar.xz archive:
+
+    git notes --ref=refs/notes/signatures/tar.xz add -C "$(
+	gpg --output - --armor --detach-sign cgit-1.1.tar.xz |
+	git hash-object -w --stdin
+    )" v1.1
+
+If it is instead desirable to attach a signature of the underlying .tar, this
+will be linked, as a special case, beside a .tar.* link that does not have its
+own signature. For example, a signature of a tarball of the latest tag might
+be added with a similar command:
+
+    tag="$(git describe --abbrev=0)"
+    git notes --ref=refs/notes/signatures/tar add -C "$(
+        git archive --format tar --prefix "cgit-${tag#v}/" "$tag" |
+        gpg --output - --armor --detach-sign |
+        git hash-object -w --stdin
+    )" "$tag"
+
+Since git-archive(1) is expected to produce stable output between versions,
+this allows one to generate a long-term signature of the contents of a given
+tag.

+Git - fast, scalable, distributed revision control system
+=========================================================
+
+Git is a fast, scalable, distributed revision control system with an
+unusually rich command set that provides both high-level operations
+and full access to internals.
+
+Git is an Open Source project covered by the GNU General Public
+License version 2 (some parts of it are under different licenses,
+compatible with the GPLv2). It was originally written by Linus
+Torvalds with help of a group of hackers around the net.
+
+Please read the file [INSTALL][] for installation instructions.
+
+Many Git online resources are accessible from <https://git-scm.com/>
+including full documentation and Git related tools.
+
+See [Documentation/gittutorial.txt][] to get started, then see
+[Documentation/giteveryday.txt][] for a useful minimum set of commands, and
+`Documentation/git-<commandname>.txt` for documentation of each command.
+If git has been correctly installed, then the tutorial can also be
+read with `man gittutorial` or `git help tutorial`, and the
+documentation of each command with `man git-<commandname>` or `git help
+<commandname>`.
+
+CVS users may also want to read [Documentation/gitcvs-migration.txt][]
+(`man gitcvs-migration` or `git help cvs-migration` if git is
+installed).
+
+The user discussion and development of Git take place on the Git
+mailing list -- everyone is welcome to post bug reports, feature
+requests, comments and patches to git@vger.kernel.org (read
+[Documentation/SubmittingPatches][] for instructions on patch submission).
+To subscribe to the list, send an email with just "subscribe git" in
+the body to majordomo@vger.kernel.org. The mailing list archives are
+available at <https://public-inbox.org/git/>,
+<http://marc.info/?l=git> and other archival sites.
+
+Issues which are security relevant should be disclosed privately to
+the Git Security mailing list <git-security@googlegroups.com>.
+
+The maintainer frequently sends the "What's cooking" reports that

+tazblog CLI
+===========
+
+My blog stores its content in DNS, spread out over three types of `TXT` entries:
+
+* `TXT _posts.blog.tazj.in.`: A sorted list of posts, serialised as a JSON list of
+  strings (e.g. `["1486830338", "1476807384"]`)
+
+* `TXT _chunks.$postID.blog.tazj.in`: JSON chunks containing the blog post text
+
+* `TXT _meta.$postID.blog.tazj.in`: JSON blob with blog post metadata
+
+All JSON blobs are base64-encoded.
+
+This CLI tool helps to update those records.
+
+Each blog post data is a series of JSON-encoded structures which follow one of
+these formats:
+
+```
+struct metadata {
+    chunks: int
+    title: string
+    date: date
+}
+```
+
+Where `chunks` describes the number of chunks following this format:
+
+```
+struct chunk {
+    c: int
+    t: string
+}
+```
+
+Writing a blog post to DNS means taking its text and metadata, chunking it up
+and writing the chunks.
+
+Reading a blog post means retrieving all data, reading the metadata and then
+assembling the chunks in order.

+cheddar
+=======
+
+Cheddar is a tiny Rust tool that uses [syntect][] to render source code to
+syntax-highlighted HTML.
+
+It's invocation is compatible with `cgit` filters, i.e. data is read from
+`stdin` and the filename is taken from `argv`:
+
+```shell
+cat README.md | cheddar README.md > README.html
+
+```
+
+In fact, if you are looking at this file on git.tazj.in chances are that it was
+rendered by cheddar.
+
+The name was chosen because I was eyeing a pack of cheddar-flavoured crisps
+while thinking about name selection.

+Subject: [PATCH 2/3] feat(ui-summary): Attempt to use README at each subtree
+
+This means that individual subtrees of a repository will also have
+their READMEs rendered on the about page, for example:
+
+    /foo/bar/README.md
+
+Will render on:
+
+    /about/foo/bar/
+
+This is useful for monorepo setups in which subtrees represent

+Subject: [PATCH 3/3] feat(ui-shared): Generate links to about pages from
+ subtrees
+
+If you're on tree/foo/bar, the about link will now point to
+about/foo/bar.
+
+Currently the annoying thing about this is that it will also do it for
+files.
